Error in a file and problem with ptpython

[sylas]

Hi all! First trouble: python works with version 3.7 while ptpython works with verion 3.6. How make them both work with 3.7 ?
Second trouble: I have a file made by a professionnal, still I have an error.

Now the error:

[Gribouillis]

Second trouble: this code uses a module timer which we don't know where it comes from. However, I suspect it is this module from the cheeseshop, which runs this C code. As you can see in function Timer_new(), it takes at least 2 arguments: a time in microseconds and a python callback.

It is also possible that from timer import Timer invokes a different module on the author's computer and this timer module on yours, which would explain the error.

I tried this:

1 2 3 4

# Initiates Timer class object       #t = Timer()       t = Timer#added       start_time = t.start()

and the new error is:

Error:
Please input an integer: 145
Traceback (most recent call last):
  File "big.py", line 226, in <module>
    new_program()
  File "big.py", line 42, in new_program

    start_time = t.start()

Hi all! First trouble: python works with version 3.7 while ptpython works with verion 3.6. How make them both work with 3.7 ?

You have to install ptpython to 3.7.
I guess you have gotten pyenv to work now.
Then both python and pip should point to 3.7.

1 2 3 4 5 6 7

# Set python and pip to point to 3.7 mint@mint ~ $ pyenv global 3.7.0 mint@mint ~ $ python -V Python 3.7.0 mint@mint ~ $ pip -V pip 10.0.1 from /home/mint/.pyenv/versions/3.7.0/lib/python3.7/site-packages/pip (python 3.7) mint@mint ~ $

Then pip install ptpython will install to 3.7,test with which pyinstaller Terminal.

I suspect it is this module from the cheeseshop

No is this one prime_finder 0.1
New users may wonder cheeseshop

You should link to the code you use @sylas

[Gribouillis]

New users may wonder cheeseshop

Cheeseshop reminds me of python more than 20 years ago. I think it's good to introduce new users to these prehistoric times. Python has a history, there is a blog by GvR about it.

@snippsat: thanks, now python and ptpython use version 3.7.0
@all it is strange we cannot make work this professionnal file

[Gribouillis]

it is strange we cannot make work this professionnal file

Obviously, you're importing the wrong timer module. Use the timer module given in @snippsat's link.

I uploaded the pack "PrimeFinder" of the same author(Hammack). So we can forget my previous file.
