I am going through exercises using Eric pimpler's book Programming ArcGIS Pro with Python. I am running Juypter Notebook through ArcGIS Pro, the modules installed are arcpy and os.
Thank you.
Example:

Python

password = ''
while password != 'password':
    print("What is the password?")
    password = input()
print('Yes, the password is ' + password + '. You may enter.')

What is the password?
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
In [230]:
Line 4: password = input()

TypeError: 'str' object is not callable
---------------------------------------------------------------------------<

What I have tried:

Tried opening another notebook through ArcPro, copied the code and pasted it, initial success. Executed the code one more time failed. Code is all the occupies the current cell.

There is nothing wrong with that code (it works for me), so it is impossible to suggest anything. I can only assume something went wrong when you copied it into the notebook - which is a product I have never used.

If I copy and paste your code as you show it, it works fine.

But .... if I add one line, then it fails the same way you get:

Python

password = ''
input = ''
while password != 'password':
    print("What is the password?")
    password = input()
print('Yes, the password is ' + password + '. You may enter.')

It fails because I have declared a variable called input and that "overwrites" the definition of the standard function called input - so the system assumes you are trying to call a string as a function and complains.

Check your code above that, and see if you have a variable called input - and change it if you do!

Saved and closed Jupyter Notebook in ArcGIS Pro. Launched Jupyter notebook from the desktop, executed the code and had success. Open the ArcGIS Pro project again copied code from Jupyter notebook currently open through the desktop pasted and executed the code, success.
Feel a lot better now!
