if in above scenario, the correct way is to first store the modification somewhere else. Iterate the list entirely one time. Can use list.copy() or list[:] as the orignial list. Another example is looping through dictionary keys: d = {'a'=1, 'b'=2, 'c'=3} for key in d: # ...
In the for loop, we go through the dictionary. The optional if condition specifies a condition which must be met. In the end, the expression is evaluated. The expression produces elements of the output dictionary from members of the input sequence that satisfy the condition. comprehension.py #...
