Conversions between Python data types

1, string-to-integer, provided the string is a pure number.

A = ' 1 ' a = Int (a)

　　

2, integer-to-string

A= 1a = str (a)

　　

3, integer-to-float

A = 1a = float (a)

　　

4, floating-point type

A = 1.2a = Int (a)

　　

5, String goto list

A = ' abc ' A = List (a)

　　

6, List to string

list = [' A ', ' B ', ' C '] '. '. Join (List1)

　

7, String goto ancestor

A= ' abc ' a= tuple (a)

8, meta-ancestor turn string

Tuple1= (' A ', ' B ', ' C ') '. '. Join (TUPLE1)

　　

9, Ganso and list to dictionary (the element in the precondition list must consist of a list of two elements or a tuple)

List1 = ([' Name ', ' Tom '), (' Age ', '] ') ') print dict (List1)

　　

10, Dictionary converted to list

dict1={' name ': ' Tom ', ' age ': ' + '}list1 = Dict1.items ()
