Create a tuple of Python
Tuple is another ordered list, and Chinese is translated as "tuple". Tuple and list are very similar, however,once a tuple is created, it cannot be modified .
The same is the name of the class, expressed as a tuple as follows:
>>> t = (' Adam ', ' Lisa ', ' Bart ')
The only difference between creating a tuple and creating a list is the ( )
substitution [ ]
.
Now, this t
cannot be changed, thetuple has no append () method, and there is no insert () and Pop () method . Therefore, the new classmate can not directly add to the tuple, old classmates want to quit a tuple also not.
The way to get a tuple element is exactly the same as the list, and we can access the element normally using indexed methods such as t[0],t[-1] , but cannot be assigned to any other element, but it is not believed to try:
>>> t[0] = ' Paul ' Traceback (most recent): File "<stdin>", line 1, in <module>typeerror: ' Tuple ' object does not support item assignment
