Python For Loop Examples

The for loop in Python is used to iterate over a sequence (such as a list, tuple, dictionary, set, or string) and execute a block of code for each item in the sequence. Here are some examples to help you understand how for loops work in Python:

1. Iterating over a list:

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
 print(fruit)

This will output:

applernbananarncherry

1. Iterating over a range of numbers:

for i in range(5):
 print(i)

This will output:

0
1
2
3
4

1. Using enumerate() to get the index and value of items in a list:

fruits = ["apple", "banana", "cherry"]
for i, fruit in enumerate(fruits):
 print(i, fruit)

This will output:

0 applern1 bananarn2 cherry

1. Iterating over a dictionary:

person = { "name": "John", "age": 30, "city": "New York" }
for key, value in person.items():
 print(key, value)

This will output:

name Johnrnage 30
city New York

These are just a few examples of how you can use for loops in Python. You can use for loops with any sequence type and perform different actions for each item in the sequence.
