在大多数情况下，它可以完成任务，但有时（我很难精确地说，它依赖于什么）它会陷入一个无限循环中，因为它不切分文本字符串。在def insertNewlines(text, lineLength):
"""
Given text and a desired line length, wrap the text as a typewriter would.

text: a string containing the text to wrap.
line_length: the number of characters to include on a line before wrapping
the next word.
returns: a string, with newline characters inserted appropriately.

def spacja(text, lineLength):
return text.find(' ', lineLength-1)
if len(text) <= lineLength:
return text
else:
x = spacja(text, lineLength)
return text[:x] + '\n' + insertNewlines(text[x+1:], lineLength)
