pycharm:从“调试”中的标准输入读取模式 [英] pycharm: read from standard input in "debug" mode
问题描述
import sys
def read_in() :
lines = sys.stdin.readlines()
for i in range(len(lines)):
lines [i] = lines [i] .replace('\\\
' ,'')
返回行
def main():
lines = read_in()
打印行
如果__name__ == '__main__':
main()
我通常使用如下命令来调用此脚本: code> cat data.txt | python script.py 将data.txt提交到标准输入。
我的问题是如何在运行/调试配置 PyCharm以相同的方式将data.txt提供到标准输入,但是哪些可以让我使用PyCharm的真棒调试模式?我怀疑我需要正确填写脚本参数字段,但是到目前为止我已经把我拖过来了。
谢谢。
个人而言,用一个Mock替换sys.stdin.readlines(),并返回你想要的值。将其放入单元测试中,并运行单元测试。
I'm debugging this script in PyCharm:
import sys
def read_in():
lines = sys.stdin.readlines()
for i in range(len(lines)):
lines[i] = lines[i].replace('\n','')
return lines
def main():
lines = read_in()
print lines
if __name__ == '__main__':
main()
I normally call this script using a command like cat data.txt | python script.py
which feeds data.txt into Standard Input.
My question is how can I setup a "Run/Debug Configuration" in PyCharm which feeds data.txt into Standard Input in the same way, but which will allow me to use PyCharm's awesome debugging mode? I suspect that I need to correctly fill out the "Script Parameters" field -- but this has eluded me so far.
Thanks.
Personally, I'd just use patch to replace sys.stdin.readlines() with a Mock, with the return value you desire. Place that into a unit test, and run the unit test.
