this sequence of symbols is required as a password in an app:
9h/#13/'!O!Nr},w_T0 6!ws%N\c^i,4"
How can store this to a variable/string?
One easy way to store those characters in a string is to use Python's triple-quotes.
s = '''9h/#13/'!O!Nr},w_T0 6!ws%N\c^i,4"'''
If your sequence did not end with a double-quote, triple double-quotes could also have been used rather than the triple single-quotes above. The triple-quote way of showing a string is designed for tough cases like yours, with almost any combination of text characters allowed in the string. Executing the command print(s)
gives the output that you want:
9h/#13/'!O!Nr},w_T0 6!ws%N\c^i,4"
