jionIt’s like splicing a list or tuple with a string, and of course, splicing a string with a str
The result is naturally a string.
ex1：
results：
Case application:
When we read something out of a file, it’s often a list with many string elements, and if we want to convert it directly to str, we can use’. join ()
ex2:
Note: the content of jointest.txt is {‘testcase’:’case1′,’testresults’:’Pass’}.
fd.readlines()The result is [‘{‘testcase’:’case1′,’testresults’:’Pass’}’].
You can use”.join () to change to STR, that is,'{‘testcase’:’case1′,’testresults’:’Pass’}’.
If you want to change dict, you can use json.JSONDecoder.decode ().
result2:
{‘testcase’:’case1′, ‘testresults’:’Pass’}
