Use functools.reduce() to perform right-to-left function composition. The last (rightmost) function can accept one or more arguments; the remaining functions must be unary.
from functools import reduce

1.def compose(*fns):
  2.return reduce(lambda f, g: lambda *args: f(g(*args)), fns)
EXAMPLES
add5 = lambda x: x + 5
multiply = lambda x, y: x * y
multiply_and_add_5 = compose(add5, multiply)

multiply_and_add_5(5, 2) # 15

#define a function 
 Def cube(num)
      #write the formula of cube
      return num*num*num
     #give the number to calculate the cube 
     cube(3)
   # print the cube of that number simply by using print command
    print(cube(3))
     “return” keyword means that function have to return          value

 # give a name of function after def
 1.def sayhi():
      #put the statement in the function  
     2.print(“hello world”)
#call function by name:
3.sayhi()


Output: 
Hello world

   return len(lst) == len(set(lst))

y = [1,2,3,4,5]


all_unique(x) # False
all_unique(y) # True

This method gets vowels (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) found in a string.
   
#make a function:
def get_vowels(string):

#return is the keyword which means function have to return value: 
 return [each for each in string if each in 'aeiou']


#assign the words and function will return vowels words.
get_vowels('foobar') # ['o', 'o', 'a']


get_vowels('gym') # []

#define a function 
 1.Def cube(num)
      #write the formula of cube
      2.return num*num*num
     #give the number to calculate the cube 
     3.cube(3)
   # print the cube of that number simply by using print command
    4.print(cube(3))
     5.“return” keyword means that function have to return value         

def when(predicate, when_true):
  return lambda x: when_true(x) if predicate(x) else x
  
EXAMPLES
double_even_numbers = when(lambda x: x % 2 == 0, lambda x : x * 2)
double_even_numbers(2) # 4
double_even_numbers(1) # 1

  return [i for i in fn_generator([None, seed])]
  
  
EXAMPLES
f = lambda n: False if n > 50 else [-n, n + 10]
unfold(f, 10) # [-10, -20, -30, -40, -50]
