先将tuple转换为list 然后替换list数据 再转换回tuple就可以了
T = (1, 'CH', [3, 4])
t=list(T)
l=t[2]
L=tuple(l)
t[2]=L
T1=tuple(t)
print(T1)
T = (1, 'CH', [3, 4])
t=list(T)
l=t[2]
L=tuple(l)
t[2]=L
T1=tuple(t)
print(T1)

L = ['Alice', 66, 'Bob', True, 'False', 100]
i = 0
while i<len(L):
if i % 2 !=0:
print(L[i])
i += 1
i = 0
while i<len(L):
if i % 2 !=0:
print(L[i])
i += 1

names = ['11','22','33','44','55']
name_set = set(names)
print(name_set)
结果：{'22', '33', '44', '11', '55'}
name_set = set(names)
print(name_set)
结果：{'22', '33', '44', '11', '55'}

for i in L:
if i in S:
S.remove(i)
L.remove(i)
