lambda array python code example

Example 1: filter function using lambda in python

#filter function 

nums1 = [2,3,5,6,76,4,3,2]


bads = list(filter(lambda x: x>4, nums1))
print(bads)

Example 2: map function using lambda in python

# Map function 

nums1 = [2,3,5,6,76,4,3,2]
sq = list(map(lambda a : a*a, nums1))
print(sq)

Example 3: lambda function in python

Lamda is just one line anonymous function
Useful when writing function inside function
it can take multiple arguments but computes only one expression

Syntax:
   x = lambda arguments : expression

Example 4: lambda function in python

>>> def identity(x):
...     return x

These two functions do the same thing

>>> lambda x: x
