Python Loop

Loops in Python

In programming, loops are used to execute a block of code repeatedly. Python supports two main types of loops: for loops and while loops.

1. For Loop:
   • The for loop in Python is used to iterate over a sequence (such as a list, tuple, string, or range).
   • It executes a block of code for each item in the sequence.
     • for item in sequence:
       # Code block to be executed
     • Example
     • for i in range(1, 6):
       print(i)
2. While Loop:
   • The while loop in Python is used to execute a block of code as long as a condition is true.
   • It repeatedly executes the code block until the condition becomes false.

• • • while condition:
      # Code block to be executed
    • Example
    • i = 1
      while i <= 5:
      print(i)
      i += 1

1. Nested Loops:
   • In Python, you can also have loops inside other loops, known as nested loops.
   • They are used to execute a loop within another loop.
     • Example
     • for i in range(1, 4):
       for j in range(1, 4):
       print(i, j)
