Strings are written in single or double quotes. Triple quotes create multi-line strings.

Strings are sequences: s[0] is the first character, s[-1] the last.
Slicing: s[2:5] gets characters 2 to 4; s[:3], s[3:], s[::-1] (reversed).
len(s) returns the length.
in checks for a substring: "py" in "python".
Strings are immutable: you cannot change a character in place.

Key Takeaways: Python Strings

Mastering Python Strings helps you write clean and reliable Python code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

Python Strings Code Example

Python

s = "CodesInTech"
print(s[0], s[-1])
print(s[0:5])
print(s[5:])
print(s[::-1])
print(len(s))
print("Tech" in s)

for ch in "abc":
    print(ch)
