我正在嘗試打印您有資格獲得的東西，如果您沒有資格獲得其中任何一項，我正在嘗試打印您沒有資格獲得其中任何一項。但是使用此代碼，它總是將 else 與 if 一起打印PS：我1個月前開始編程。print('Task 2')print()name = str(input('Navn: '))age = int(input('Age: '))gender = str(input('Gender (f for female, m for male): '))children = int(input('How many children: '))repute = int(input('repute, on a scale from 1(bad) to 9(immaculate): '))record = str(input('record (done time/convicted/suspect/clean): '))seniority = int(input('seniority (years): '))print()member = gender == 'f' and age >= 20 and repute <= 7solder = gender == 'f' and age >= 20 and age <= 30 and repute <= 7 and children == 0sargent = gender == 'f' and age >= 20 and age <= 30 and repute <= 7 and children == 0 and seniority >= 4 and record != 'clean'captain = gender == 'f' and age >= 20 and age <= 40 and repute <= 7 and seniority >= 6 and record == ('done time' or 'convicted')commander = gender == 'f' and age >= 20 and age <= 40 and repute <= 3 and seniority >= 6 and record == ('done time' or 'convicted')president = gender == 'f' and age >= 20 and age <= 40 and repute <= 2 and seniority >= 8 and record == ('done time' or 'convicted') and name != 'kim'print('You are eligible to become:')if member == True: print('Member')if solder == True: print('Solder')if sargent == True: print('Sargent')if captain == True: print('Captain')if commander == True: print('Commander')if president == True: print('President')else: print('You are not eligible to be a member')

使用最終if條件來檢查是否沒有任何條件匹配，而不是else：
if member == True:
print('Member')
if solder == True:
print('Solder')
if sargent == True:
print('Sargent')
if captain == True:
print('Captain')
if commander == True:
print('Commander')
if president == True:
print('President')
if not (member or solder or sargent or captain or commander or president):
print('You are not eligible to be a member')
編輯：修改為打印所有符合條件的職位。

你可以替換
else:
print('You are not eligible to be a member')
和
if all([not cond for cond in [member, soldier, sargent, captain, commander, president]]):
print('You are not eligible to be a member')
甚至按照評論的建議，使用生成器表達(dá)式，以獲得理論上更好的性能
if all(not cond for cond in [member, soldier, sargent, captain, commander, president]):
print('You are not eligible to be a member')

只是多了一個選項，因此，如果您必須添加更多可能性，您只需將它們插入中間，而不必更改任何其他語句。
msg = []
if member:
msg.append('Member')
if solder:
msg.append('Soldier')
..
..
if new_possibility:
msg.append('blah')
if msg:
print print '\n'.join(msg)
else:
print 'Not elligible'
