Looping through variables and setting them

[snippsat]

Using eval and exec is for sure not the way to go.
Think of what happen when do pos1 = 1

>>> pos1 = 1
>>> pos1
1

Internally  is python storing this a dictionary.

>>> globals()
{'__name__': '__main__', 'pos': 1,}
>>> globals()['pos1']
1

We should not do the tricks and using the globals() dictionary.
Making a normal visible dictionary is the way to go.

>>> d = {}
>>> for i in range(1,9):
...     d[f'pos{i}'] = i
...
    
>>> d
{'pos1': 1,
 'pos2': 2,
 'pos3': 3,
 'pos4': 4,
 'pos5': 5,
 'pos6': 6,
 'pos7': 7,
 'pos8': 8}

>>> d['pos1']
1
