how to read a long multiline string line by line in python
提问by DKean
I have a wallop of a string with many lines. How do I read the lines one by one with a forclause? Here is what I am trying to do and I get an error on the textData var referenced in the for line in textDataline.
我有一个多行的字符串冲击。如何用for子句逐行阅读？这是我正在尝试执行的操作，并且在该for line in textData行中引用的 textData var 上出现错误。
for line in textData
print line
lineResult = libLAPFF.parseLine(line)
The textData variable does exist, I print it before going down, but I think that the pre-compiler is kicking up the error.
textData 变量确实存在，我在关闭之前打印它，但我认为预编译器正在引发错误。

What about using .splitlines()?
怎么用.splitlines()？
for line in textData.splitlines():
print(line)
lineResult = libLAPFF.parseLine(line)

by splitting with newlines.
通过用换行符分割。
for line in wallop_of_a_string_with_many_lines.split('\n'):
#do_something..
if you iterate over a string, you are iterating char by char in that string, not by line.
如果您迭代一个字符串，那么您是在该字符串中逐个字符地迭代，而不是逐行。
>>>string = 'abc'
>>>for line in string:
print line
a
b
c

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines()is the way to go. I will leave this answer nevertheless as reference.
这个答案在几个边缘情况下失败（见评论）。上面接受的解决方案将处理这些。str.splitlines()是要走的路。尽管如此，我还是会留下这个答案作为参考。
Old (incorrect) answer:
旧（不正确）答案：
s = \
"""line1
line2
line3
"""
lines = s.split('\n')
print(lines)
for line in lines:
print(line)
