Explain Return Statement in Python

A return statement signals the end of a function’s execution, sending back the result (the value of the expression following the return keyword) to the caller. Anything after the return statement won’t be executed. When a return statement lacks an expression, it returns the special value None. Ultimately, a return statement is how a function is activated, allowing the execution of the provided statements.

Note: Return statements are only used inside functions.

Syntax:

def tmp():
    statement
  return [ expression ]
Here, I've given you an example in which the return statement performs an operation and returns a value.

Example:

# Python program to demonstrate return statement

def add(x, y):
# returning sum of x and y
  return x + y
def is_true(x):
# returning boolean of x
  return bool(x)
# calling the function
tmp = add(2, 3)
print(f"Result of add function is {tmp}")
tmp = is_true(2<5)
print(f"\nResult of is_true function is {tmp}")

Output:

Here I gave you another example of which you can return multiple values using the object.

Example:

# A Python program to return multiple values from a method using class 
class tmp: 
  def __init__(self): 
    self.str = "AccuCloud"
    self.val = 20
# This function returns an object of tmp 
def func(): 
  return tmp()
# creating object of the func() 
a = func() 
print(a.str) 
print(a.val)

Output:

You can also return value using a tuple. A Tuple consists of items separated by commas and can be created both with or without parentheses. Tuples, once created, cannot be changed (they are immutable).

Example:

# A Python program to return multiple values from a method using tuple 
def tmp(): 
  stri = "Accu Cloud"
  a = 20
  return str, a; # Returning tuple
# Driver code to test above method 
stri, x = tmp() 
print(stri) 
print(x)

Output:

Example:

# A Python program to return multiple values from a method using list
def tmp():
stri = "Accu Cloud"
a = 10
return [stri, a];
list1 = tmp()
print(list1)

Output:

You can also return the dictionary. A Dictionary shares similarities with hashes or maps found in other programming languages.

Example:

# A Python program to return multiple values from a method using dictionary
def tmp(): 
  a = dict(); 
  a['stri'] = "Accu Cloud"
  a['z'] = 10
  return a
  a = tmp() 
print(a)

Output:

Here I have given you an example of which functions are like objects, so we can send back a function from another function. This works because, in Python, functions are treated as super flexible objects.

Example:

def fun1(a):
  def adder(b):
    return a + b
  return adder
adding = fun1(15)
print("The result is", adding(20))
def tmp(x):
  return x * 10
def my_func1():
  return tmp
res = my_func1()
print("Result is:", res(20))

Output:

Conclusion:

The return statement in Python helps us send back values from functions to the place they were called. It’s like handing over a package of information before the function finishes its job.
