f-string

Learn to embed variables in text with f"...".

An f-string is the modern way to embed variables or expressions inside a string. Put an f before the string and write variables inside {}:

name = "Alex"
print(f"Hello {name}")  # Hello Alex

f-strings were added in Python 3.6 and are the most common method today. You can also write expressions in the braces: f"Total: {3 + 5}".

f-string formatting

You can also format inside an f-string. After : you specify the format:

price = 19.99
print(f"Price: {price:.2f}")  # Price: 19.99
print(f"Percent: {0.85:.0%}")   # Percent: 85%

:.2f gives two decimals, :.0% gives a percentage. This is very handy for tables and reports.

Assign name = "Alex" and age = 25. Print print(f"{name} is {age}").
