Since PyCharm knows which file is "main", how can I tell it "run this project"

[sylas]

Hi all ! Since PyCharm knows which file is "main", how can I tell it: "run this project"(instead of "run this file") ? Here below the 2 files. Amazing ! ; no "import" present.
 

#minmax2.py
print('I am:', __name__)

def minmax(test, *args):
    res = args[0]
    for arg in args[1:]:
        if test(arg, res):
            res = arg
    return res

def lessthan(x, y): return x < y
def grtrthan(x, y): return x > y

if __name__ == '__main__':
    print(minmax(lessthan, 4, 2, 1, 5, 6, 3))    # Self-test code
    print(minmax(grtrthan, 4, 2, 1, 5, 6, 3))
'''
output
/usr/bin/python3.5 /home/sylvain/PycharmProjects/minmax/minmax2.py
I am: __main__
1
6
'''

Now the second:

#minmax.py
def minmax(test, *args):
    res = args[0]
    for arg in args[1:]:
        if test(arg, res):
            res = arg
    return res

def lessthan(x, y): return x < y                # See also: lambda
def grtrthan(x, y): return x > y

print(minmax(lessthan, 4, 2, 1, 5, 6, 3))       # Self-test code
print(minmax(grtrthan, 4, 2, 1, 5, 6, 3))
'''
output
/usr/bin/python3.5 /home/sylvain/PycharmProjects/minmax/minmax.py
1
6
'''

This section of the code:

if __name__ == '__main__':
    print(minmax(lessthan, 4, 2, 1, 5, 6, 3))    # Self-test code
    print(minmax(grtrthan, 4, 2, 1, 5, 6, 3))

is only run if starting if the module is called directly, by pressing run in PyCharm,
or from command line by typing:

python minmax.py

Thanks for your reply Larz60. I tried with the terminal "python min.py". It works well. But I don't understand your reply concerning PyCharm. Where in this enormous PyCharm must I go in order to run the whole project ??

[Larz60+]

In PyCharm upper right corner is the run button with a pull-down list.
you select the module you want to run, then click the run button.

but ...

The first time, you must:

• 1. Click anywhere in module.
  
• 2. Click on run menu (in top menu)
  
• 3. Select Run or press Alt-Shift-F10.
  
• 4. After first time, the module will be i the pull-down list.

In the pull-down list I have 4 items: EditConfigurations,saveminmax2configuration,minmax,minmax2....................The choice belongs to me.Does the "saveminmax2configuration" means: I know minmax2 is the main, and you save it  if you like  ?????

[Larz60+]

You must click in the module you wnt to run first (step 1).
It sounds like you are clicking in the command window

I think I found how to run the whole project, in PyCharm. You open your project. On the top at left, in the menu bar, you have: 1. Run (with main file name). 2. Debag (with main file name 3.Run   4. Debug......The third is the good one for running the whole project.

[Larz60+]

It's a good debugger.
You can step into or run step by step displayin whatever you wish.
there is also a Run command on the same meny. If you have first
clicked i the source code window, you cane use that to run the entire module
or entire package if you start with the top level module, and have the proper imports in place.
