is there such a thing? I know that tuple needs to be added when there is only one element, and whether list is added or not is the same.
a=[1,2,3]
b=[1,2,3,]
print(a)
print(b)
print(a==b)
a.append(1)
b.append(1)
print(a)
print(b)
print(a==b)
def test(c):
print(type(c))
test((1,))
test((1))
test(a)
test(b) there is no difference between the two results, but when passing parameters to the function, Python will do different processing
such as (12) and (12,), but there is no difference in passing parameters in the list. The running result is as follows
