Check if a string is in a file with Python
提问by Gleyak
I'm new to Python and I'm trying to figure out how I can search for a string in a file and use it as a condition in a if clause: If "String" is in the file, Print("Blablabla")
我是 Python 新手，我试图弄清楚如何在文件中搜索字符串并将其用作 if 子句中的条件：如果“字符串”在文件中，则 Print("Blablabla")

As you yourself said, just open the file and check if it is in it.
正如您自己所说，只需打开文件并检查它是否在其中。
with open('myfile.txt') as myfile:
if 'String' in myfile.read():
print('Blahblah')
Isn't Pythondelightful?
是不是Python赏心悦目？

This is the top answer from a very similar question.
if 'blabla' in open('example.txt').read():
print "true"
