必须按两次回车才能运行python

tablou = input("Introduceti valori separate cu spatiu: ")

b = tablou.split()

extrema = input("Gasesc valoarea (min)ima sau (max)ima?: ")

t = [] # initial list with int() contents

for l in b:

r = int(l)

t.append(r)

def main0():

t.sort()

return t[0]

def main1():

t.sort(reverse= True)

return t[0]

valoare = input()

if extrema.lower() == "min":

valoare = main0()

elif extrema.lower() =="max":

valoare = main1()

print(valoare)

代码应该接受整数输入并显示最大/最小的元素。我怀疑问题是在最后6行，但在我看来，一切都是正确的，感谢帮助！
