Here z is a variable in which the input dictionary is stored and string is the key of the input dictionary. input_dict: Takes a single parameter which is the input dictionary.


Returns key’s values of the input dictionary.

Example 1: Python String format_map() method

# input stored in variable a.
a = {'x':"geeksforgeeks", 'y':'b'}
# Use of format_map() function
print('{x} {y}'.format_map(a))
