Python program to wrap a text into paragraph with width w

Text wrapping is a common task when formatting output for display or printing. Python's textwrap module provides the fill() function to wrap text into paragraphs with a specified width.

Syntax

textwrap.fill(text, width=70, **kwargs)

Parameters

The fill() function accepts the following parameters:

• text − The string to be wrapped

• width − Maximum line width (default is 70)

• break_long_words − Break words longer than width (default True)

• break_on_hyphens − Break on hyphens (default True)

Basic Text Wrapping

Let's wrap a text string with width 9 ?

import textwrap

def wrap_text(text, width):
    return textwrap.fill(text, width)

text = "The quick brown fox jumps over the lazy dog"
width = 9
result = wrap_text(text, width)
print(result)

The quick
brown fox
jumps
over the
lazy dog

Different Width Examples

Here's how the same text looks with different widths ?

import textwrap

text = "The quick brown fox jumps over the lazy dog"

# Different widths
widths = [15, 20, 30]

for w in widths:
    print(f"Width {w}:")
    print(textwrap.fill(text, w))
    print("-" * w)

Width 15:
The quick brown
fox jumps over
the lazy dog
---------------
Width 20:
The quick brown fox
jumps over the lazy
dog
--------------------
Width 30:
The quick brown fox jumps
over the lazy dog
------------------------------

Advanced Options

Control word breaking and hyphen handling ?

import textwrap

text = "This is a super-long-hyphenated-word example"

# Default behavior
print("Default:")
print(textwrap.fill(text, 20))
print()

# Don't break on hyphens
print("break_on_hyphens=False:")
print(textwrap.fill(text, 20, break_on_hyphens=False))
print()

# Don't break long words
print("break_long_words=False:")
print(textwrap.fill(text, 20, break_long_words=False))

Default:
This is a super-long-
hyphenated-word
example

break_on_hyphens=False:
This is a super-long-
hyphenated-word
example

break_long_words=False:
This is a super-long-hyphenated-word
example

Conclusion

Use textwrap.fill() to wrap text into paragraphs with specified width. The function intelligently breaks at word boundaries and provides options for handling long words and hyphens.
