Try commenting out these lines:
ent1w1 = ent1w1.get()
ent2w1 = ent2w1.get()
ent3w1 = ent3w1.get()
and the one in the while loop.
You’ve already called .get on them, which presumably returns a Python native float. But ttk.Button that you passed the entw1 to might call .get on DoubleVa…

Thanks. Moreover, I can’t understand that why the “while” and also “if” statements results in wrong outputs. The statements do not give correct answers.

Try this instead,
print(
"{:.3f}% {} ({} sentences)".format(pcent, gender, nsents)
)
Refer the latest docs for more examples and check the Py version!

You could also use {:.3%} instead of {:.3f}%.
It will transform the value into percentages automatically.
That means "{:.3%}".format(0.3) will print "30%" while you have to write "{:.3f}%".format(0.3 * 100) to get "30%" as well.

r/learnpython on Reddit: Timemodule not working
January 15, 2022 -
Hi just a quick one for any python pros, i have just started using python 3. I am reading the documentation for the datetime module and trying to practice with it, however alot of the code that im trying doesnt actually seem to work.
For example, in the documentation is this example:
>>> from datetime import date
>>> date.fromisoformat('2019-12-04')
datetime.date(2019, 12, 4)
However when i copy the same code, i get this error message
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
date.fromisoformat('2019-12-04')
AttributeError: type object 'datetime.date' has no attribute 'fromisoformat'
Any advice/help is much appreciated, thanks.

it works for me. if u do the from datetime import date help(date) u will see that it has the method. fromisoformat(...) from builtins.type | str -> Construct a date from the output of date.isoformat()

How to fix AttributeError: object has no attribute - GeeksforGeeks
July 23, 2025 - To understand this error, we first have to know how to read the error message effectively. It typically consists of two parts: "AttributeError" and "Object has no attribute." The former indicates the type of error, and the latter suggests that the attribute we are trying to access does not exist for the object.
