You use for with an iteraterable.
for item in [1, 2, 3]:

for i, l in enumerate([1, 2, 3])

for i in range(1, 10)

and a for loop takes a bool:

while 1 < 2:

hi there!

let me explain them to you:

for loops

A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).

for example:

for i in range(5): #will repeat for 5 times
  # remember to indent
  print("Hello")

output:

Hello
Hello
Hello
Hello
Hello

another example: a countdown program

import time

countdown = 60 # setting a variable for the countdown
for i in range(60): # repeats 60 times
  print("Countdown: "+str(countdown)) # prints what number we are at
  countdown -= 1	# takes 1 off the countdown (because it has been counted)
  time.sleep(1) #waits 1 sec before continuing

output:

Countdown: 60
Countdown: 59
Countdown: 58
Countdown: 57
Countdown: 56
Countdown: 55
Countdown: 54
# etc until Countdown = 1

while loops

With the while loop we can execute a set of statements as long as a condition is true.

example:

while True:
  print("Hello")

output:

Hello
Hello
Hello
Hello
Hello

# until infinity

another example: a sort of password guesser:

password = 100 #sets the password

guess = input("guess password: ") #asks for the guss

while guess != password: #keeps on going until password is found
  print("try again!") 
  guess = input("guess password: ") 

  if guess == "100": # if user finds password
    print("youve guessed it!")
    break #ends the loop

output:

@ParthChawla Hi again,
As you said, Here is my own definition:-
There are two types of Loops:-

1. While Loop

A While Loop is basically a structure in Python which allows us to loop through and execute a block of code multiple times.

Correct syntax of writing a While Loop:

i = 1
while i <= 10:
  print(i)
  i+=1

print('Done with While Loop!')

2. For Loop

A For Loop is a special type of loop in Python which allows us to loop over a different collection of items. It can be used in strings, numbers, and etc...

Correct syntax of writing a For Loop

for letter in "Hello World\n":
  print(letter)

If you need theory beyond these types, Comment me!
Thanks!

Hope this helps

Hello, there is no "real" for loop in python. Here's the closest thing:

// C
for (int i = 0; i < 10; i ++) { /* ... */ }

for i in range(10):
  # code

However, a while loop behaves as you expect.
