Python: Format text paragraphs with textwrap

Python’s textwrap module is useful for rearranging text, e.g. wrapping and filling lines.

# Wrap the text in the string "parallel", so that all lines are a maximum of x characters long:

# When x = 2
textwrap.wrap("parallel", width=2)
# Output:
# ['pa', 'ra', 'll', 'el']

# When x = 4
textwrap.wrap("parallel", width=4)
# Output:
# ['para', 'llel']

# If we would like to include trailing newlines (\n) after each string of a certain width
# we can either use the following syntax:

'\n'.join(textwrap.wrap('text', width=2))
# Output:
# 'te\nxt'

# Or we can use the fill method implemented in `textwrap` module:

textwrap.fill("text", width=2)
# Output:
# 'te\nxt'

# Fill a text:

textwrap.fill(text, width=55)

# Collapse and truncate a text to width :

print(textwrap.shorten
("Hello world!", width=12))
print(textwrap.shorten
("Hello world!", width=11))
# Hello world!
# Hello [...]

# The last words are dropped if the text is longer than the width argument.

# Other useful methods like indent and dedent are available in this module.
