Python: String Operations

What you will learn

Common string methods and f-strings for formatting.

text = "  Hello, World!  "
text.lower()            # "  hello, world!  "
text.upper()            # "  HELLO, WORLD!  "
text.strip()            # "Hello, World!" (removes whitespace)
text.split(",")         # ["  Hello", " World!  "]
text.replace("World", "Python")  # "  Hello, Python!  "
" ".join(["a", "b"])    # "a b"
len(text)               # 16 (includes spaces)

f-strings (Python 3.6+)

name = "Alice"
age = 25
print(f"{name} is {age} years old.")
print(f"Next year, {name} will be {age + 1}.")

f-strings evaluate expressions inside { } and insert the result into the string. They are the preferred way to format strings in modern Python.
