为什么字典不打印更新后的值 Python 3.6

每次在输入字段中输入“g”时，字典“goal-totals”都应该更新，并且新值反映在打印的“totals”输出中。除了第一次输入条目“g”外，该代码均有效。如何使第一个条目反映在打印的“总计”输出中？

from IPython.display import clear_output
     
goal_totals = {'goals' :0}              
active = True
while active:
  totals = f'Goals: {goal_totals["goals"]}'
  
  command = input()
  if command == 'g':
    goal_totals["goals"] += 1
    clear_output()
    print(totals)

Each time 'g' is entered into the input field, the dictionary 'goal-totals' should be updated and the new value reflected in the printed 'totals' output. The code works all but for the first time an entry 'g' is entered. How do I make the first entry reflect in the printed 'totals' output?

from IPython.display import clear_output
     
goal_totals = {'goals' :0}              
active = True
while active:
  totals = f'Goals: {goal_totals["goals"]}'
  
  command = input()
  if command == 'g':
    goal_totals["goals"] += 1
    clear_output()
    print(totals)

试试这个，应该有帮助。

代码每次更新后都会计算总数。

from IPython.display import clear_output
     
goal_totals = {'goals' :0}              
active = True
while active:
    command = input()
    if command == 'g':
        goal_totals["goals"] += 1
    totals = f'Goals: {goal_totals["goals"]}'
    clear_output()
    print(totals)

Try this, it should help.

The code calculates the totals each time after its updated.

from IPython.display import clear_output
     
goal_totals = {'goals' :0}              
active = True
while active:
    command = input()
    if command == 'g':
        goal_totals["goals"] += 1
    totals = f'Goals: {goal_totals["goals"]}'
    clear_output()
    print(totals)
