map and filter function in python is pretty different because they perform very differently. Let's have a quick example to differentiate them.
map function
Let's define a function which will take a string argument and check whether it presents in vowel letter sequences.
def lit(word):
return word in 'aeiou'
Now let's create a map function for this and pass some random string.
for item in map(lit,['a','b','e']):
print(item)
And yes it's equivalent to following
lit('a') , lit('b') , lit('e')
simply it will print
True
False
True
filter function
Now let's create a filter function for this and pass some random string.
for item in filter(lit,['a','b','e']):
print(item)
filter as the name implies, filters the original iterable and retents the items that return True for the function provided to the filter function.
Simply it will print
a
e
