mapping python code example

Example 1: mapping in python string

# mapping function
def uppercase(u):
    return str(u.upper())

map_iterator = map(uppercase,['a','b','c'])
mylist = list(map_iterator)
print(mylist)

Example 2: map function in python

# Python program to demonstrate working 
# of map. 
  
# Return double of n 
def addition(n): 
    return n + n 
  
# We double all numbers using map() 
numbers = (1, 2, 3, 4) 
result = map(addition, numbers) 
print(list(result))

Example 3: map in python

'''try this instead of defining a function'''

a = [1,2,3,4]
a = list(map(lambda n: n+n, a))

print(a)

Example 4: python dictionary map function

dictionary = {k: f(v) for k, v in dictionary.items()}

Example 5: pyhton map

def calculateSquare(n):
    return n*n


numbers = (1, 2, 3, 4)
result = map(calculateSquare, numbers)
print(result)

# converting map object to set
numbersSquare = list(result)
print(numbersSquare)

Example 6: python map

map(function_to_apply, list_of_inputs)
