How to check if a tuple contains an element in Python?
提问by Joan Venge
I tried to find the available methods but couldn't find it. There is no contains
. Should I use index
? I just want to know if the item exists, don't need the index of it.
我试图找到可用的方法,但找不到。没有contains
。我应该使用index
吗?我只想知道该项目是否存在,不需要它的索引。

Be careful with that: return Oops. use Set: d= {...}
小心:返回哎呀。使用集合:d= {...}
def simha():
d = ('this_is_valid')
b = 'valid'
if b in d:
print("Oops!!!!!")
simha()

if "word" in str(tuple):
# You can convert the tuple to str too
i has the same problem and only worked to me after the convert str()
我有同样的问题,只有在转换 str() 后才对我有用
