將某些內容添加到列表中的代碼

Question

pitch = input('Please enter the pitch of the note: ') 
pitch = int(pitch) 
time = input('Please enter the duration of the pitch in seconds: ') 
time = int(time) 

event 1 = [music[-1][0], pitch, 'On'] # when I run this error occurs here, event 1. 
event 2 = [music[-1][0]+ time, pitch, 'Off'] 

music.append(event 1) 
music.append(event 2) 

print(music) 
displaymusic() 

如何修復錯誤？這是將音符添加到音樂列表的代碼。

Answer 1

event和數字之間不能有空格。讓這樣的代碼：

pitch = input('Please enter the pitch of the note: ') 
pitch = int(pitch) 
time = input('Please enter the duration of the pitch in seconds: ') 
time = int(time) 

event1 = [music[-1][0], pitch, 'On'] 
event2 = [music[-1][0]+ time, pitch, 'Off'] 

music.append(event1) 
music.append(event2) 

print(music) 
displaymusic() 

在Python中，變量必須以下劃線或字母開頭，然後被下劃線，數字或字母完全由。變量名稱中的空格會導致非法語法。
