String Alignment in Python f-string

Last Updated : 22 Mar, 2025

String alignment in Python helps make text look neat and organized, especially when printing data of different lengths. Without formatting, output can appear messy and hard to read. Python’s f-strings make it easy to align text by controlling its position within a set space. Python’s f-strings allow text alignment using three primary alignment specifiers:

< (Left Alignment): Aligns the text to the left within the specified width.
> (Right Alignment): Aligns the text to the right within the specified width.
^ (Center Alignment): Centers the text within the specified width.

Each alignment specifier is followed by a width number, which determines how much space is reserved for the string.

Example: Left-aligned (<), Right-aligned (>) and Center-aligned (^)

Python

s = "Hello" print(f"{s:<10}World") print(f"{s:>10}World") print(f"{s:^10}World")

Output

Hello     World      HelloWorld   Hello   World

Explanation: < specifier left-aligns “Hello”, so spaces are added to the right. The > specifier right-aligns “Hello”, meaning spaces are added before it. The ^ specifier centers “Hello”, adding an equal number of spaces on both sides.

Examples of String Alignment in Python f-strings

Example 1: Aligning Multiple Variables in a Table-Like Format

Python

a = "Alice" b = 25  # Left-aligned (<), Right-aligned (>), and Center-aligned (^) print(f"Name: {a:<10} Age: {b:>5} ") print(f"Name: {a:^10} Age: {b:^5} ")

Output

Name: Alice      Age:    25  Name:   Alice    Age:  25

Explanation: “Alice” is left-aligned in 10 spaces and age 25 is right-aligned in 5 spaces for consistency. The second print statement centers both within their widths.

Example 2: Displaying List Data in a Structured Table

Python

d = [("Alice", 25, "USA"), ("Char", 22, "Chicago")]  print(f"{'Name':<10}{'Age':<5}{'City':<10}")  for name, age, city in d:     print(f"{name:<10}{age:<5}{city:<10}")

Output

Name      Age  City       Alice     25   USA        Char      22   Chicago

Explanation: Column headers are left-aligned for a neat presentation. The loop aligns values within fixed-width columns, ensuring organized output with consistent spacing.

Example 3: Handling dynamic width

Python

a = ["Apple", "Banana", "Cherry"] max_width = max(len(word) for word in a) + 2 for word in a:     print(f"{word:<{max_width}} - Fruit")

Output

Apple    - Fruit Banana   - Fruit Cherry   - Fruit

Explanation: max_width dynamically calculates the longest word’s length plus 2 spaces for padding, ensuring left-aligned, consistently spaced and readable output.

Example 4: String padding for enhanced formatting

Python

s = "Python" print(f"{s:-^20}") print(f"{s:*<15}") print(f"{s:=>15}")

Output

-------Python------- Python********* =========Python

Explanation: The first print statement centers “Python” within 20 spaces, filling the empty space with -. The second line left-aligns “Python” within 15 spaces, filling the remaining space with *. The third line right-aligns “Python” within 15 spaces, filling the left side with =.
