Python的標(biāo)準(zhǔn)數(shù)據(jù)類型非常簡(jiǎn)單就以下幾種：
Python：標(biāo)準(zhǔn)數(shù)據(jù)類型：Number单匣，String,List[],Tuple()元祖,Dict{}
#Number分為整數(shù)int和浮點(diǎn)float
x1 = 13
x2 = 13.0
print(x1,x2)
print(x1+x2)
print(type(x1),type(x2))
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
13 13.0
26.0
<class 'int'> <class 'float'>
#String字符串
x1 = 'hello'
x2 = 'world'
#多行字符串
x3 = '''a
b
c
'''
print(x1,x2)
print(x3)
print(type(x3))
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
hello world
a
b
c
<class 'str'>
#Bool布爾型
a = True
b = False
print(a == 1)
print(b == 1)
print(b == 0)
3 > 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
True
False
True
Out[5]:True
#列表：用[]標(biāo)識(shí)的有序的對(duì)象，支持?jǐn)?shù)字，字符串以及嵌套列表
lst1 = [1,3,4,6,7]
print(lst1)
lst2 = [1,4,5,'hello',lst1]
print(lst2)
print(lst2[4],type(lst2[4]))
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(1, 4, 5, 6, 9) <class 'tuple'>
[100, 4, 5, 6, 9] <class 'list'>
#字典Dict：用｛｝標(biāo)識(shí)
dict1 = {'a':100, 'b':'你那呢'}
print(dict1)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{'a': 100, 'b': '你那呢'}
#數(shù)據(jù)類型轉(zhuǎn)換方法 **int float str 三種 list/tuple/dict后面總結(jié)
var1 = 10
print(type(var1))
var2 = float(var1)
print(var2,type(var2))
var3 = str(var2)
print(var3,type(var3))
print(var2 + 1)
print(var3 + '1')
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<class 'int'>
10.0 <class 'float'>
10.0 <class 'str'>
11.0
10.01
