Tuple creation
Deletion of tuples
The output of some elements of tuples
Nesting of tuples
Calculation of the number of tuple elements ：len()
Solving the maximum and minimum values of elements in tuples ：max(),min()
The number of occurrences of an element in a tuple ：count function
The index of an element in a tuple ：index(）, Returned is a subscript value
Modification of tuple element value ： Element values of tuples cannot be modified .
Tuple creation
tuple=() # Create an empty tuple print(tuple)print(type(tuple))Output ：
()
<class 'tuple'>
Define tuples that contain only one element ： The element must be followed by a comma , Otherwise the compiler will recognize it as an integer .
give an example ：
tuple2 = (1,)print(tuple2)print(type(tuple2))tuple2 = (1)print(tuple2)print(type(tuple2))Output ：
Deletion of tuples(1,)
<class 'tuple'>
1
<class 'int'>
del Tuple name to be deleted
tuple2 = (1,2,3,4,5,6)print(tuple2)del tuple2print(tuple2)
Because we are in the third line of code for tuple2 Deleted , So the compiler will report an error ,tuple2 Not defined .
Determine whether an element is in a tuple ：in/ not in sentence
give an example ：
tuple2 = (1,2,3,4,5,6)if 4 in tuple2: print("YES")else: print("NO")if 10 in tuple2: print("YES")else: print("NO")Output :
The output of some elements of tuplesYES
NO
Similar to slicing a list .
give an example ：
tuple2 = (1,2,3,4,5,6)print(tuple2[0:3])Output ：
Nesting of tuples(1, 2, 3)
Similar to the nesting of lists , Just replace the list with tuples
give an example ：
tuple1=((1,2,3),(4,5,6),(7,8,9))for tuple1s in tuple1: print(tuple1s) for tuple1_s in tuple1s: print(tuple1_s)Output ：
Calculation of the number of tuple elements ：len()(1, 2, 3)
1
2
3
(4, 5, 6)
4
5
6
(7, 8, 9)
7
8
9
give an example ：
tuple1=(1,2,3,4,5,6,7,8,9)print(len(tuple1))Output ：
Solving the maximum and minimum values of elements in tuples ：max(),min()9
give an example ：
tuple1=(1,2,3,4,5,6,7,8,9)print(max(tuple1))print(min(tuple1))Output ：
The number of occurrences of an element in a tuple ：count function9
1
give an example ：
tuple1=(1,2,3,4,5,6,7,8,9,3,3,2,2)print(tuple1.count(3))Output ：
The index of an element in a tuple ：index(）, Returned is a subscript value3
give an example ：
tuple1=(1,2,3,4,5,6,7,8,9,3,3,2,2)print(tuple1.index(2))Output ：
Modification of tuple element value ： Element values of tuples cannot be modified .1
give an example ：
tuple1=(1,2,3,4,5,6,7,8,9,3,3,2,2)tuple1[3]=100print(tuple1)Output ：
