Change the value of a variable inside a loop in python

Change the value of a variable inside a loop in python

You can change the value of a variable inside a loop in Python by simply assigning a new value to that variable within the loop. Here's a basic example:

# Initialize a variable my_variable = 0 # Loop 5 times and increment the variable in each iteration for i in range(5): my_variable += 1 print("Iteration", i+1, ": my_variable =", my_variable) # After the loop, the value of my_variable has changed print("Final value of my_variable:", my_variable)

In this example, we start with my_variable set to 0. Inside the for loop, we increment my_variable by 1 in each iteration. After the loop, you can see that the value of my_variable has changed to 5.

You can modify the variable's value inside the loop according to your specific needs. The key is to use the assignment operator (=) to give it a new value within the loop.
