Loops

#description

In Python, loops allow you to repeat a set of instructions until a specific condition is met. There are mainly two types of loops in Python: for and while loops.

for loops iterate over a sequence of data (such as a list or a string) and execute the same code block for each element in the sequence.

The syntax for a for loop is as follows:

 
                    
for variable in sequence:
    # code to be executed

while loops, on the other hand, continue to execute a block of code as long as a certain condition remains true.

The syntax for a while loop is as follows:

 
                    
while condition:
    # code to be executed

Loops are very useful for automating repetitive tasks such as processing large amounts of data or performing calculations. They can also be used to streamline your code and make it more efficient by reducing the amount of duplicated code.
