Python data type

Python contains 6 of the standard types:
1.Number Numeric type
2.String String Type
3.List list Types
4.Tuple tuple Type
5.Dict Dictionary Type
6.Set collection type
Note: In addition to the standard data types, Python has an unlimited number of data types because users can create their own
"""

#1. Number numeric type
‘‘‘
1.int integer Integer
2.float floating-point float
3.complex Complex Complex
4.bool boolean bool
‘‘‘
#1. Integral type is an integer, including positive integer/negative integer/0
#十进制声明整数 (0-9)
Intvar = 25
Print (Intvar)
Print (Type (Intvar))

#声明二进制整数 (0-1)
Intvar = 0b10011101
Print (Intvar)
Print (Type (Intvar))

#声明八进制整数 (0-7)
Intvar = 0o532
Print (Intvar)
Print (Type (Intvar))

#声明十六进制整数 (0~9A-F)
Intvar = 0x32f
Print (Intvar)
Print (Type (Intvar))

#2. Floating-point numbers are decimals.
Floatvar = 3.2
Print (Type (Floatvar))

Floatvar = 325e-2
Print (Type (Floatvar))

#3. plural
Fsvar = 3-2j
Print (Type (Fsvar))

Fsvar = Complex (2,9)
Print (Fsvar)
Print (Type (Fsvar))

#4. BOOL Type
RST = 30<5
Print (Type (RST))

Boolvar = False
Print (Type (Boolvar))

#String String Type
#字符串类型就是文字类型

#单引号声明字符串
Strvar = ' Wanke '
Print (Strvar,type (Strvar))

#双引号声明字符串
Strvar = "Wanda"
Print (Strvar,type (Strvar))

#三引号声明字符串
#strvar = "CEO CEO"
Strvar = "" CFO Chief Financial officer ""
Print (Strvar,type (Strvar))

#三种引号使用的场合
#字符串中包含双引号但不包括单引号时, single quotation marks should be used to declare
Strvar = ' Zifuchuanzhong ' Baohan ' Shuangyinhao '
Print (Strvar)

#字符串中包含单引号但不包括双引号时, you should use double-quote declarations
Strvar = "He likes to eat ' shopping"
Print (Strvar)

When #字符串中包含单/double quotes, use a three-quote declaration
Strvar = "My good friend", and you are also "good friends". ‘‘‘
Print (Strvar)

Print (home) print (' 3xiao ')
