Python，分割字符串

我有一个大的字符串文本文件，我想分割每117个字符的字符串，并将下一个117个字符放在换行符上，依此类推直到文件结束。Python，分割字符串

我尝试这样做：`S = “” “ 我已删除了可视性原因字符串 ”“” 空间= “” “

”“” 文件=打开（ 'testoutput.txt' ， 'W'）而S：打印S [10] 输出=输出+ S + “””

""" 
s = s[10:]

file.write（输出） file.close（）印刷 “完成” `

，但有该文件的最终输出看起来像这样级联的问题：'此[SHIFT] R后退键分子及其后代将AV，因为突变后退键后退键改变

T]r[BACKSPACE]molecule and its descendants would av[BACKSPACE][BACKSPACE]vary because of mutations

while s: 
    print s[:117] 
    s = s[117:]

您可以使用常规切片语法分割缓冲区，或者你可以选择在阅读它直接将文件拆分。这是第二种方法的一个例子：

with open(r"/path/to/some/file") as input_file: 
    line = input_file.read(117) 
    while line: 
     print len(line) 
     line = input_file.read(117)
