Python String format_map() Method Last Updated : 05 Aug, 2021 Comments Improve Suggest changes Like Article Like Report Python String format_map() method is an inbuilt function in Python, which is used to return a dictionary key's value. Syntax: string.format_map(z) Parameters: 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: Returns key's values of the input dictionary. Example 1: Python String format_map() method Python3 # input stored in variable a. a = {'x':'John', 'y':'Wick'} # Use of format_map() function print("{x}'s last name is {y}".format_map(a)) Output: John's last name is WickExample 2: Python3 # input stored in variable a. a = {'x':"geeksforgeeks", 'y':'b'} # Use of format_map() function print('{x} {y}'.format_map(a)) Output: geeksforgeeks bExample 3: Python3 # Input dictionary profession = { 'name':['Barry', 'Bruce'], 'profession':['Engineer', 'Doctor'], 'age':[30, 31] } # Use of format_map() function print('{name[0]} is an {profession[0]} and he' ' is {age[0]} years old.'.format_map(profession)) print('{name[1]} is an {profession[1]} and he' ' is {age[1]} years old.'.format_map(profession)) Output: Barry is an Engineer and he is 30 years old. Bruce is an Doctor and he is 31 years old.Example 4: Practical Application The format_map() function can be used in any practical application. Python3 # Python code showing practical # use of format_map() function def chk_msg(n): # input stored in variable a. a = {'name':"George", 'mesg':n} # use of format_map() function print('{name} has {mesg} new messages'.format_map(a)) chk_msg(10) Output: George has 10 new messages Comment More infoAdvertise with us Next Article Python String casefold() Method K Kanchan_Ray Follow Improve Article Tags : Python python-dict Python-Built-in-functions python-string Practice Tags : pythonpython-dict Similar Reads Python String Methods Python string methods is a collection of in-built Python functions that operates on strings.Note: Every string method in Python does not change the original string instead returns a new string with the changed attributes.
