Finding a specific line in a file - Vqlk - Sep-07-2019
I have created a login app and have started work on a forgotten password module. I want to change the password in a txt file. The passwords will differ. The text file looks like:
username:
door
first name:
Random
last name:
person
age:
111
password:
saaS`1112
email:
[email protected]
i want to be able to change the password (not the line that says password but the one below it) line to a different string. Is this possible?

maybe something like this
text = """username: door first name: Random last name: person age: 111 password: saaS`1112 email: [email protected]""" pw = text.partition("password:\n")[2].partition("\nemail:")[0] newpassword = "python" newtext = text.replace(pw, newpassword) print(newtext)
Output:username:
door
first name:
Random
last name:
person
age:
111
password:
python
email:

You should know how to open a textfile.
change the path ( i've used /tmp/test.txt)
with open("/tmp/test.txt", 'r') as f:
text = f.read()
f.close()
pw = text.partition("password:\n")[2].partition("\nemail:")[0]
newpassword = "python"
newtext = text.replace(pw, newpassword)
print(newtext)
with open("/tmp/test.txt", 'w') as f:
f.write(newtext)
f.close
