Flowchart For Swapping Two Values Using Functions In Python

Contents

Develop a flowchart for swapping two values using functions

In this program, we will learn to swap two numbers using functions.

Algorithm:

Step1: Start
Step2: Declare the variables a, b, and read the inputs.

Step3: Call the function swap(a,b)
Step4: The function performs the following steps.
- t=a
- a=b
- b=t
Step5: print Swapped numbers are: a b.

Step6: End.

Flowchart to swap two numbers

Python program to swap two numbers in a list

// Take two integer input value
a = int ( input ( " enter your number a : "))
b = int ( input ( " enter your number b : "))
# n2 = eval ( input ( " enter your second number : ")) # in this you can take any types of user input
n1 = a
a = b
b = n1
print (" After swap the number b is : ",b)
print (" After swap the number a is : ",a)

Input and Output

enter your number a : 100
 enter your number b : 200
 After swap the number b is :  100
 After swap the number a is :  200

How do you swap two numbers without using a temporary variable in Python?

To switch two variables first we have to declare two variables.
Example
var1 = 5
var2 = 7
print (“Before swapping: “)
print(“Value of var1 : “, var1, “\nValue of var2 : “, var2)
code to swap ‘var1’ and ‘var2’
var1, var2 = var2, var1
print (“After swapping: “)
print(“Value of var1 : “, var1, “\nValue of var2 : “, var2)
Output:
Before swapping:
Value of var1 : 5
Value of var2 : 7
After swapping:
Value of var1 : 7
Value of var2 : 5

How do you switch two variables in Python?

To swap values in python, we have to declare two variables and one temporary variable. Example
temp = a
a = b
b = temp
