Python Strings

Strings are used to store text data in Python. A string is a sequence of characters enclosed in single quotes or double quotes.

name = "Python"
message = 'Hello World'

1. Basic Syntax 
Strings can be created using single or double quotes.

name = "Alex"
city = 'Mumbai'

Both are valid strings.

2. Access Characters using Indexing 
Each character has an index starting from 0.

text = "Python"
print(text[0])
print(text[3])

Output: 
P 
h

Negative indexing starts from the end.

print(text[-1])

Output: 
n

3. String Slicing 
Extract part of a string using slicing.

text = "Python"
print(text[0:3])
print(text[2:6])

Output: 
Pyt 
thon

4. String Length 
Use len() to find the number of characters.

text = "Python"
print(len(text))

Output: 
6

5. Convert Case 

text = "Python Programming"
print(text.upper())
print(text.lower())
print(text.title())

Output: 
PYTHON PROGRAMMING 
python programming 
Python Programming

6. Remove Spaces 
Use strip() to remove leading and trailing spaces.

text = " Python "
print(text.strip())

Output: 
Python

7. Replace Text 

text = "I love Java"
print(text.replace("Java", "Python"))

Output: 
I love Python

8. Split a String 
Convert a string into a list.

text = "Python SQL Excel"
print(text.split())

Output: 
['Python', 'SQL', 'Excel']

9. Join Strings 
Join list elements into a single string.

words = ["Python", "SQL", "Excel"]
print(" | ".join(words))

Output: 
Python | SQL | Excel

10. Check String Methods

text = "Python"
print(text.startswith("Py"))
print(text.endswith("on"))
print("th" in text)

Output: 
True 
True 
True

11. String Concatenation 
Combine multiple strings using +.

first = "Hello"
second = "World"
print(first + " " + second)

Output: 
Hello World

12. f-Strings Recommended 
The easiest way to format strings.

name = "Alex"
age = 25
print(f"My name is {name} and I am {age} years old.")

Output: 
My name is Alex and I am 25 years old.

Note: f-Strings are faster and more readable than string concatenation.

13. Practice Examples

Reverse a string 

text = "Python"
print(text[::-1])

Output: 
nohtyP

Count occurrences 

text = "banana"
print(text.count("a"))

Output: 
3

Find character position 

text = "Python"
print(text.find("t"))

Output: 
2

Check if string contains a word 

text = "I am learning Python"
print("Python" in text)

Output: 
True

Note: Strings are one of the most frequently used data types in Python, especially in web development, automation, and data analysis.
