Need help in understanding the below python string extraction

Question

I read the below code about string extraction in python

text[text.find("insert"):(len(text),text.find("Configure"))[text.find("Configure")>1]]

and I am not able to understand this part

(len(text),text.find("Configure"))[text.find("Configure")>1]

How does this work? Can some one help me?

Answer 1

There are several pieces of code involved in this one line:

I am considering variable text is of str type

1. (len(text),text.find("Configure")) This code will return a tuple of int, example: (100, 10)
2. [text.find("Configure")>1] This code will return a list of bool either [True] or [False]
3. Now combining both code blocks above, if index of "Configure" is greater than 1 then it will be True i.e. 1 so element in tuple at index 1 will be taken i.e. 10, else condition will be False i.e. 0 so element at index 0 will be taken i.e. 100 (from the example tuple defined above)

(len(text),text.find("Configure"))[text.find("Configure")>1]

4. The whole line boils down to:

text[text.find("insert"):100]

or

text[text.find("insert"):10]

and this is basic string slicing in Python
