How to solve the problem "TypeError: setEnabled(self, bool): argument 1 has unexpected type 'str'"?

Question

I have encountered such a problem `

> python .\main.py
Traceback (most recent call last):
  File "C:\main.py", line 79, in writeF
    self.ui.lineEdit.setEnabled(value)
TypeError: setEnabled(self, bool): argument 1 has unexpected type 'str'

` My code is hosted on github, here's the repo link.

The relevant file part:

I'm starting to learn Python. I have developed a program that reads data from the user in the GUI via pyqt5 and qt designer, writes this data to a file output.txt. But I ran into a problem that gives an error in the command line, which I showed above. What did I do wrong

Answer 1

Short Answer: You are overwriting the previously defined value of value in line 61.

---

Longer answer: Consider this minimized example:

value = True
dictionary = {'foo': 'bar', 'baz': 'qwurx'}
for key, value in dictionary.items():
    print(key, value)
print(value, type(value))

Output:

# foo bar
# baz qwurx
# qwurx <class 'str'>

The issue is that you re-defined value in the loop on every call. The value-variable shadows and overwrites the outer one.

---

To find such things on your own next time: The error message is already a good hint. It tells you that the method expects a boolean value, but got a string instead. Now go back from the given line to find where the variable is set last...

Concerning coding style: Your code contains a lot of generic namings, like a dictionary called dictionary and variables called values. Think of more meaningful names to prevent such issues. See Clean Naming for further thoughts on this.
