How to update a variable in python 3.6 to that of a string of text in a .txt file

Question

Say I want to update 3 variables.

X_Variable_1 X_Variable_2 X_Variable_3

(No these aren't the real names of the variables, but just for example)

Here is the text file's contents

Test Test True

I want X_Variable_1 to be updated to the 1st line of text, overwriting anything else on there, X_Variable_2 happening a similar way, except the second line of text in the file, and then X_Variable_3 being updated to the 3rd line of text

So in this manner, it should update them to

X_Variable_1 = ('Test')
X_Variable_2 = ('Test')
X_Variable_3 = (True)

Thanks

Try this:

#!/usr/bin/python
X_Variable_1, X_Variable_2, X_Variable_3 = open("FILENAME").readlines()

Or if you want the variables not to have '\\n' chars at the end, do this:

#!/usr/bin/python
X_Variable_1, X_Variable_2, X_Variable_3 = [line.rstrip() for line in open("FILENAME").readlines()]

If you have more lines than 3, you can discard all additional lines in the file as well:

#!/usr/bin/python
X_Variable_1, X_Variable_2, X_Variable_3, *_ = [line.rstrip() for line in open("FILENAME").readlines()]

In all examples, set "FILENAME" to the file name you want to read, with or without the path (either relative or absolute).
