Example 1: map function in python
def addition(n):
return n + n
numbers = (1, 2, 3, 4)
result = map(addition, numbers)
print(list(result))
Example 2: 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 3: pyhton map
def calculateSquare(n):
return n*n
numbers = (1, 2, 3, 4)
result = map(calculateSquare, numbers)
print(result)
numbersSquare = list(result)
print(numbersSquare)
Example 4: map in python
map(functions, iterables)
Example 5: map in python
def addition(n):
return n + n
numbers = (1, 2, 3, 4)
result = map(addition, numbers)
print(list(result))
Example 6: Python Map function
>>> def doubleOrNothing(num):
... return num * 2
>>> map(doubleOrNothing, [1,2,3,4,5])
<map object at 0x7ff5b2bc7d00>
>>> list(map(doubleOrNothing, [1,2,3,4,5])
[2, 4, 6, 8, 10]
>>> list(map(lambda x: x*2, [1,2,3,4,5]))
[2, 4, 6, 8, 10]
