Generate a random number between 1 and 100 To generate a whole number (integer) between one and one hundred use We can do the same thing with a list of stringsTyping string values in Python code is fairly straightforward: They begin and end with a single quote. But then how can you use a quote inside a string? Typing 'That is Alice's cat.' won’t work, because Python thinks the string ends after Alice, and the rest (s cat.') is invalid Python code. Fortunately, there are multiple ways to type strings. Welcome to Faker’s documentation!¶ Faker is a Python package that generates fake data for you. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you. The string can be defined as the sequence of characters represented in the quotation marks. In Python, we can use single, double, or triple quotes to define a string. String handling in Python is a straightforward task since Python provides built-in functions and operators to perform operations in the string.
