language_locale_codes
locale() str

Generate a random underscored i18n locale code (e.g. en_US).

language_code() str

Generate a random i18n language code (e.g. en).

random_int(min: int = 0, max: int = 9999, step: int = 1) int

Generate a random integer between two integers min and max inclusive while observing the provided step value.

This method is functionally equivalent to randomly sampling an integer from the sequence range(min, max + 1, step).

Sample

min=0, max=15

Sample

min=0, max=15, step=3

random_digit() int

Generate a random digit (0 to 9).

random_digit_not_null() int

Generate a random non-zero digit (1 to 9).

random_digit_above_two() int

Generate a random digit above value two (2 to 9).

random_digit_or_empty() Union[int, str]

Generate a random digit (0 to 9) or an empty string.

This method will return an empty string 50% of the time, and each digit has a 1/20 chance of being generated.

random_digit_not_null_or_empty() Union[int, str]

Generate a random non-zero digit (1 to 9) or an empty string.

This method will return an empty string 50% of the time, and each digit has a 1/18 chance of being generated.

random_number(digits: Optional[int] = None, fix_len: bool = False) int

Generate a random integer according to the following rules:

  • If digits is None (default), its value will be set to a random integer from 1 to 9.

  • If fix_len is False (default), all integers that do not exceed the number of digits can be generated.

  • If fix_len is True, only integers with the exact number of digits can be generated.

Sample

fix_len=False

Sample

fix_len=True

Sample

digits=3

Sample

digits=3, fix_len=False

Sample

digits=3, fix_len=True

random_letter() str

Generate a random ASCII letter (a-z and A-Z).

random_letters(length: int = 16) Sequence[str]

Generate a list of random ASCII letters (a-z and A-Z) of the specified length.

Sample

length=10

random_lowercase_letter() str

Generate a random lowercase ASCII letter (a-z).

random_uppercase_letter() str

Generate a random uppercase ASCII letter (A-Z).

random_elements(elements: ElementsType[T] = ('a', 'b', 'c'), length: Optional[int] = None, unique: bool = False, use_weighting: Optional[bool] = None) Sequence[T]

Generate a list of randomly sampled objects from elements.

Set unique to False for random sampling with replacement, and set unique to True for random sampling without replacement.

If length is set to None or is omitted, length will be set to a random integer from 1 to the size of elements.

The value of length cannot be greater than the number of objects in elements if unique is set to True.

The value of elements can be any sequence type (list, tuple, set, string, etc) or an OrderedDict type. If it is the latter, the keys will be used as the objects for sampling, and the values will be used as weighted probabilities if unique is set to False. For example:

# Random sampling with replacement
fake.random_elements(
    elements=OrderedDict([
        ("variable_1", 0.5),        # Generates "variable_1" 50% of the time
        ("variable_2", 0.2),        # Generates "variable_2" 20% of the time
        ("variable_3", 0.2),        # Generates "variable_3" 20% of the time
        ("variable_4": 0.1),        # Generates "variable_4" 10% of the time
    ]), unique=False
)

# Random sampling without replacement (defaults to uniform distribution)
fake.random_elements(
    elements=OrderedDict([
        ("variable_1", 0.5),
        ("variable_2", 0.2),
        ("variable_3", 0.2),
        ("variable_4": 0.1),
    ]), unique=True

randomize_nb_elements(number: int = 10, le: bool = False, ge: bool = False, min: Optional[int] = None, max: Optional[int] = None) int

Generate a random integer near number according to the following rules:

  • If le is False (default), allow generation up to 140% of number. If True, upper bound generation is capped at 100%.

  • If ge is False (default), allow generation down to 60% of number. If True, lower bound generation is capped at 100%.

  • If a numerical value for min is provided, generated values less than min will be clamped at min.

  • If a numerical value for max is provided, generated values greater than max will be clamped at max.

  • If both le and ge are True, the value of number will automatically be returned, regardless of the values supplied for min and max.

Sample

number=100

Sample

number=100, ge=True

Sample

number=100, ge=True, min=120

Sample

number=100, le=True

Sample

number=100, le=True, max=80

Sample

numerify(text: str = '###') str

Generate a string with each placeholder in text replaced according to the following rules:

  • Number signs (‘#’) are replaced with a random digit (0 to 9).

  • Percent signs (‘%’) are replaced with a random non-zero digit (1 to 9).

  • Dollar signs (‘$’) are replaced with a random digit above two (2 to 9).

  • Exclamation marks (‘!’) are replaced with a random digit or an empty string.

  • At symbols (‘@’) are replaced with a random non-zero digit or an empty string.

Under the hood, this method uses random_digit(), random_digit_not_null(), random_digit_or_empty(), and random_digit_not_null_or_empty() to generate the random values.

Sample

text=’Intel Core i%-%%##K vs AMD Ryzen % %%##X’

Sample

text=’!!! !!@ !@! !@@ @!! @!@ @@! @@@’

lexify(text: str = '????', letters: str = string.ascii_letters) str

By default, letters contains all ASCII letters, uppercase and lowercase.

Sample

text=’Random Identifier: ??????????’

Sample

text=’Random Identifier: ??????????’, letters=’ABCDE’

bothify(text: str = '## ??', letters: str = string.ascii_letters) str

Generate a string with each placeholder in text replaced according to the following rules:

  • Number signs (‘#’) are replaced with a random digit (0 to 9).

  • Question marks (‘?’) are replaced with a random character from letters.

By default, letters contains all ASCII letters, uppercase and lowercase.

Under the hood, this method uses numerify() and and lexify() to generate random values for number signs and question marks respectively.

Sample

letters=’ABCDE’

Sample

text=’Product Number: ????-########’

Sample

text=’Product Number: ????-########’, letters=’ABCDE’

Sample

text=’MAC Address: ^^:^^:^^:^^:^^:^^’

Sample

text=’MAC Address: ^^:^^:^^:^^:^^:^^’, upper=True

Bases: faker.providers.BaseProvider

Implement default credit card provider for Faker.

For all methods that take card_type as an argument, a random card type will be used if the supplied value is None. The list of valid card types includes 'amex', 'diners', 'discover', 'jcb', 'jcb15', 'jcb16', 'maestro', 'mastercard', 'visa', 'visa13', 'visa16', and 'visa19'.

Sources:

prefix_maestro: List[str] = ['5018', '5020', '5038', '56##', '57##', '58##', '6304', '6759', '6761', '6762', '6763', '0604', '6390']

luhn_lookup
credit_card_provider(card_type: Optional[CardType] = None) str

Generate a credit card provider name.

credit_card_number(card_type: Optional[CardType] = None) str

Generate a valid credit card number.

credit_card_expire(start: faker.typing.DateParseType = 'now', end: faker.typing.DateParseType = '+10y', date_format: str = '%m/%y') str

Generate a credit card expiry date.

This method uses |date_time_between| under the hood to generate the expiry date, so the start and end arguments work in the same way here as it would in that method. For the actual formatting of the expiry date, |strftime| is used and date_format is simply passed to that method.

credit_card_full(card_type: Optional[CardType] = None) str

Generate a set of credit card details.

credit_card_security_code(card_type: Optional[CardType] = None) str

Generate a credit card security code.

_credit_card_type(card_type: Optional[CardType] = None) CreditCard

Generate a random CreditCard instance of the specified card type.

_generate_number(prefix: str, length: int) str

Generate a credit card number.

The prefix argument is the start of the CC number as a string which

may contain any number of digits. The length argument is the length of the CC number to generate which is typically 13 or 16.
