使用 textwrap 模块来格式化字符串的输出。比如,假如你有下列的长字符串:
s = "Look into my eyes, look into my eyes, the eyes, the eyes, \
the eyes, not around the eyes, don't look around the eyes, \
look into my eyes, you're under."
下面演示使用 textwrap 格式化字符串的多种方式:
>>> import textwrap
>>> print(textwrap.fill(s, 70))
Look into my eyes, look into my eyes, the eyes, the eyes, the eyes,
not around the eyes, don't look around the eyes, look into my eyes,
you're under.
>>> print(textwrap.fill(s, 40))
Look into my eyes, look into my eyes,
the eyes, the eyes, the eyes, not around
the eyes, don't look around the eyes,
look into my eyes, you're under.
>>> print(textwrap.fill(s, 40, initial_indent=' '))
Look into my eyes, look into my
eyes, the eyes, the eyes, the eyes, not
around the eyes, don't look around the
eyes, look into my eyes, you're under.
>>> print(textwrap.fill(s, 40, subsequent_indent=' '))
Look into my eyes, look into my eyes,
the eyes, the eyes, the eyes, not
around the eyes, don't look around
the eyes, look into my eyes, you're
under.
