Loops are used to execute a block of code repeatedly.
The main types are,
- For loops
- While loops.
Syntax:
While loop:
while (condition):
# code block
For loop:
for (variable) in (sequence):
# code block
While loop:
While loop repeatedly executes a block of code as long as the given condition remains true. When the condition becomes false, it will terminate the loop and print the remaining.
Example: While Loop
1).
i= 1
while i<= 5:
print("Number:", i)
i+= 1
This code is used to print the numbers from 1 to 5.
2).
i= 1
while i<= 10:
print("Number:", i*2)
i+= 1
This code is used to print multiples of 2.
3).
i= 1
fact = 1
while i<=5:
fact = fact * i
i= i + 1
print("Factorial of 5 is:", fact)
This code is used to print factorial of a number.
For loop:
A for loop is used to repeat a block of code for a fixed number of times
for (variable) in (sequence):
# code block
Example: For Loop
n = [1,2,3,4,5]
for x in n:
print(x)

The article covers the basics of "for" and "while" loops in Python well, but it would be great to see more on handling edge cases, like nesting or working with large datasets. If you're into DSA problems or coding interviews, PracHub has a good set of questions that explore these scenarios. It's a nice advantage over just using LeetCode, especially when preparing for technical rounds.
