      Change Dictionary Items

      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.

      Change Dictionary Items

      Apart from the literal representation of dictionary, where we put comma-separated key:value pairs in curly brackets, we can create dictionary object with built-in dict() function.

      Empty Dictionary

      Using dict() function without any arguments creates an empty dictionary object. It is equivalent to putting nothing between curly brackets.

      Example

      d1 = dict()
      d2 = {}
      print ('d1: ', d1)
      print ('d2: ', d2)
      It will produce the following output
      d1: {}
      d2: {}

      Dictionary from List of Tuples

      The dict() function constructs a dictionary from a list or tuple of two-item tuples. First item in a tuple is treated as key, and the second as its value.

      Example

      d1=dict([('a', 100), ('b', 200)])
      d2 = dict((('a', 'one'), ('b', 'two')))
      print ('d1: ', d1)
      print ('d2: ', d2)
      It will produce the following output 
      d1: {'a': 100, 'b': 200}
      d2: {'a': 'one', 'b': 'two'}

      Dictionary from Keyword Arguments

      The dict() function can take any number of keyword arguments with name=value pairs. It returns a dictionary object with the name as key and associates it to the value.

      Example

      d1=dict(a= 100, b=200)
      d2 = dict(a='one', b='two')
      print ('d1: ', d1)
      print ('d2: ', d2)
      It will produce the following output 
      d1: {'a': 100, 'b': 200}
      d2: {'a': 'one', 'b': 'two'}
