  • Check if an element is an array.
exampleList = ["one", "two", "three"]
thisIsTrue = "one" in exampleList
  • Python's string.isalnum() is used to check if a string is an alphabet or a numeric.
  • Python's string.isdigit() is used to check if a string is a digit. For example "0019".isdigit() will return True.

  • Python's string.isnumeric() is used to check if a string is a digit. For example "0019".isnumeric() will return False. But "19".isnumeric() will return True.

  • Example of Docopt.
