Strings are one of the most important topics in Python programming, especially for Class 11 students. Almost every program you write involves text handling, making strings a must-learn concept.
To help you understand this topic easily, we have created detailed Strings in Python Class 11 Notes in PDF format, designed for beginners as well as exam preparation.
What Are Strings in Python?
A string in Python is a sequence of characters enclosed in quotes. These characters can be letters, numbers, or symbols.
Example:
name = “Python”
Strings are widely used in:
-
- Text processing
- User input handling
- Data storage
- Web development

Example Program
# Program to check palindrome
text = input(“Enter a string: “)
if text == text[::-1]:
print(“Palindrome”)
else:
print(“Not Palindrome”)
