Beginner's Tutorial on for Loop in Python
Introduction
In Python, a for loop is a control flow statement. It allows you to execute a block of code multiple times. It is used for iterating over a sequence (like a list, tuple, string, or dictionary) or other iterable objects.
Basic Syntax
Python
for variable in iterable:
# code block to be executed
variable
will take each value from theiterable
one by one.iterable
is the sequence or iterable object you want to loop over.code block
is the block of code that will be executed for each value in theiterable
.
Examples
Example 1:Loop Over a List
Python
fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
Output:
Python
apple
banana
cherry
Example 2: Looping Over a Range
The range()
function generates a sequence of numbers
Python
for i in range(5):
print(i)
Output:
Python
