Doubt about pycharm

I typed exactly this:

import math
num = float(input('Digite um numero: '))
print('A parte inteira do numero {} é {}.'.format(num, math.trunc(num)))

However, when running, this only appears:

Digite um numero: 9.8

Process finished with exit code 0

I would like to know why I can not display what I typed in the third line.
