Python Data Types Explained (I) String

I. Basic data types

Integer: int
String: str (Note: \t is equal to a tab key)
Boolean: bool
List: list
List with []
Metazoan: tuple
Genjo used ()
Dictionary: dict

Note: All data types exist in the class columns that you want to correspond to.

II. String all data types:

Basic Operations:

Index, Slice, Append, Delete, Length, Slice, Loop, Contains

class str(object):
  """
  str(object='') -> str
  str(bytes_or_buffer[, encoding[, errors]]) -> str
  
  Create a new string object from the given object. If encoding or
  errors is specified, then the object must expose a data buffer
  that will be decoded using the given encoding and error handler.
  Otherwise, returns the result of object.__str__() (if defined)
  or repr(object).
  encoding defaults to ().
  errors defaults to 'strict'.
