      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      String

      In Python, a string is an immutable sequence of Unicode characters. Each character has a unique numeric value as per the UNICODE standard. But, the sequence as a whole, doesn't have any numeric value even if all the characters are digits. To differentiate the string from numbers and other identifiers, the sequence of characters is included within single, double or triple quotes in its literal representation. Hence, 1234 is a number (integer) but '1234' is a string.
      As long as the same sequence of characters is enclosed, single or double or triple quotes don't matter. Hence, following string representations are equivalent.
      >>> 'Welcome To TutorialsPoint'
      'Welcome To TutorialsPoint'
      >>> "Welcome To TutorialsPoint"
      'Welcome To TutorialsPoint'
      >>> '''Welcome To TutorialsPoint'''
      'Welcome To TutorialsPoint'
      >>> """Welcome To TutorialsPoint"""
      'Welcome To TutorialsPoint'
      Looking at the above statements, it is clear that, internally Python stores strings as included in single quotes.
      A string in Python is an object of str class. It can be verified with type() function.
      var = "Welcome To TutorialsPoint"
      print (type(var))
      It will produce the following output
      <class 'str'>
      You want to embed some text in double quotes as a part of string, the string itself should be put in single quotes. To embed a single quoted text, string should be written in double quotes.
      var = 'Welcome to "Python Tutorial" from TutorialsPoint'
      print ("var:", var)
      
      var = "Welcome to 'Python Tutorial' from TutorialsPoint"
      print ("var:", var)
      To form a string with triple quotes, you may use triple single quotes, or triple double quotes − both versions are similar.
      var = '''Welcome to TutorialsPoint'''
      print ("var:", var)
      
      var = """Welcome to TutorialsPoint"""
      print ("var:", var)
      Triple quoted string is useful to form a multi-line string.
      var = '''
      Welcome To
      Python Tutorial
      from TutorialsPoint
      '''
      print ("var:", var)
      It will produce the following output
      var:
      Welcome To
      Python Tutorial
      from TutorialsPoint
      A string is a non-numeric data type. Obviously, we cannot use arithmetic operators with string operands. Python raises TypeError in such a case.
      >>> "Hello"-"World"
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
      TypeError: unsupported operand type(s) for -: 'str' and 'str'
