I. Basic data types
Integer: int
String: str (note: \ t equals a TAB key)
Boolean value: BOOL
  Listing: List
list with []
Ganso: Tuple
For Ganso ()
Dictionary: Dict
Note: All data types exist in the class column that you want to correspond to.

Two. List all data types:

Basic operation:

    • Index
    • Slice
    • Additional
    • Delete
    • Length
    • Slice
    • Cycle
    • Contains

Three. Examples of all list data types

Four. Index

Name_list = ["Zhangyanlin", "suoning" "Aylin" "Nick"]print (Name_list[0])

Five. Slicing

Name_list = ["Zhangyanlin", "suoning" "Aylin" "Nick"]print (Name_list[0:2])

Six. Total length len

Name_list = ["Zhangyanlin", "suoning" "Aylin" "Nick"]print (Name_list[1:len (name_list)])

Seven. For loop

Name_list = ["Zhangyanlin", "suoning" "Aylin" "Nick"]for I in Name_list:print (i)
