For example, in 3457, I would like to choose the third digit (5) and multiply it by three. How would I do this? I have tried changing digits to strings and then going from their however it didn't go well.
Let's say we have this integer:
num = 3457
To select specific numbers, let's first convert it to string.
num_str = str(num)
Now we can select the third character.
third_digit = num_str
Before multiplying it, we have to convert it back to integer.
print(int(third_digit) * 3)
