Which of the following options is referred to as the for loop in Python?
Answer (2)
In Python programming, a 'for' loop is used to iterate over a sequence (such as a list, tuple, or string) or other iterable objects. The 'for' loop allows you to execute a block of code multiple times, once for each element in the sequence.
Here's a simple breakdown of the 'for' loop in Python:
Syntax : The basic structure of a 'for' loop in Python looks like this:
for element in iterable: # Do something with element
element is a variable that takes the value of the item inside the iterable on each iteration.
iterable is the collection you are looping over. This could be a list, a tuple, or even a string.
The block of code inside the loop will be executed for each item in the iterable.
Example : Here's an example of a 'for' loop that prints each number in a list:
numbers = [1, 2, 3, 4, 5]
for number in numbers: print(number)
This loop will print each number from 1 to 5.
Use Cases : The 'for' loop is particularly useful when you need to perform operations on items of a collection without modifying the original iterable. It's also widely used in data processing and automation.
The 'for' loop is a fundamental concept in programming and is essential for automating repetitive tasks efficiently.
A 'for' loop in Python is used to iterate over a sequence or iterable object, allowing you to execute a block of code for each item. The syntax enables you to define an element that takes the value of each item in the iterable as the code runs. This structure is particularly useful for automating repetitive tasks and is widely applied in programming.
