      Python String expandtabs() – Replace Tabs with Spaces

      Python String expandtabs() Method

      The expandtabs() method in Python is used with string objects. It replaces all tab characters (\t) in a string with spaces. You can also set the number of spaces a tab should expand to.

      Syntax

      string.expandtabs(tabsize=8)

      Parameters:

      • tabsize – (Optional) The number of spaces to replace each \t with. Default is 8.

      Returns:

      • A new string where all \t tab characters are replaced with spaces.

      Example 1: Default Tab Size

      text = "Python\tRocks!"
print(text.expandtabs())
      Python  Rocks!

      Example 2: Custom Tab Size (tabsize=4)

      text = "A\tB\tC"
print(text.expandtabs(4))
      A   B   C

      Example 3: With Multiple Tabs and Alignment

      data = "Name\tAge\tCity"
print(data.expandtabs(10))
      Name      Age       City

      Why Use expandtabs()?

      • To make tabbed text align nicely using spaces
      • Useful in formatting outputs, reports, or logs
      • Helps standardize formatting across systems (tabs can display differently in different editors)

      Common Mistakes

      • Forgetting that expandtabs() doesn’t modify the original string (strings are immutable)
      • Using it without understanding how tab size works with alignment (it aligns to the next multiple of tab size)

      Interview Tip

      This method might come up in string formatting problems where you need to normalize or align data.

      Summary

      • expandtabs() replaces \t with spaces
      • Default tab size is 8, but you can customize it
      • Returns a new string (does not change original)

      Practice Challenge

      Write a Python program that takes a tab-separated string from user input and prints the expanded version using 6 spaces per tab.

      user_input = input("Enter a tab-separated string: ")
print(user_input.expandtabs(6))
