Python For vs While Loops: Key Differences

The for loop and while loop are both used to repeatedly execute a piece of code, but they have some differences.

for loop:

1. The for loop is used to iterate through the elements of an iterable object (such as a list, tuple, dictionary, etc.) and perform the same operation on each element.
2. The for loop is typically used in situations where the number of iterations is known, such as iterating through elements in a list or performing a fixed number of operations.
3. For loop syntax: for item in iterable (where item represents each element, and iterable represents the iterable object)

A while loop:

1. The while loop continues to execute the code within its body based on a condition, until the condition is no longer met.
2. The while loop is typically used in situations where the number of iterations is uncertain, such as repeatedly asking for user input or determining whether to continue based on a specific condition.
3. While loop syntax: while condition: (where condition represents the loop condition)

In general, for loops are suitable for handling situations where the number of iterations is known, while while loops are suitable for handling situations where the number of iterations is unknown. When deciding which loop structure to use, it is important to consider the specific situation.
