Pthon基本數據類型

Python基本數據類型包括：

• 數字 Number
• 字符串 String
• 列表 List
• 元組 tuple
• 字典 Dictionary
• 集合 Set

數字 Number

# coding=utf-8

a = 100    # 整型變量
b = 100.0  # 浮點型變量

print(a)
print(b)

字符串 String

# coding=utf-8

name = "小明"
age = '18歲'
des = """小明18歲"""
other='''小明18歲'''

print(name)
print(age)
print(des)
print(other)

列表 List

# coding=utf-8

number_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
letter_list = ['a', 'b', 'c', 'd']
mix_list = [1, 'a', 2, 'b', 3, 'c']
nest_list = [1, 'a', [2, 'b'], 3, ['c']]

print(number_list)
print(letter_list)
print(mix_list)
print(nest_list)

元組 Tuple

# coding=utf-8

number_tuple = (1, 2, 3, 4, 5, 6)
letter_tuple = ('a', 'b', 'c', 'd')
mix_tuple = (1, 'a', 2, 'b', 3, 'c')
nest_tuple = (1, 'a', (2, 'b'), 3, ('c'))

print(number_tuple)
print(letter_tuple)
print(mix_tuple)
print(nest_tuple)

字典 Dictionary

# coding=utf-8

dict1 = {'a': 1, "b": 2, "c": 3}
dict2 = {1: 'a', 2: 'b', 3: 'c'}

print(dict1)
print(dict2)

集合 Set

# coding=utf-8

development_tool = {'AndroidStudio', 'PyCharm', 'IDEA', 'Eclipse'}

print(development_tool)
