# Toolby: PyCharm

# 定义变量就会开辟内存空间

# 变量:定义世间万事万物

name = 'mage, jason'
height = 180
weight = 140
hobby = ['piao','liang']

# 变量就应该要有各种各样的数据类型

# 数字

## 整型
a = 11
b = 12

## 浮点型
height1 = 1.8

# 数字有什么用:加减乘除

print(a + b)
print(a - b)
print(a * b)
print(a / b)

# 字符串:一个单词一个单词,一句话一句话(一串字母)

name1 = 'nick' # 把一串字符包在 '',""
name2 = "xiaomage"
name3 = "I'm tank"
print(name3)

shi = '''
纸上得来终觉浅,绝知此事要躬行;
我觉得这都是假的,我只想躺平
'''
print(shi)
shi = """
纸上得来终觉浅,绝知此事要躬行;
我觉得这都是假的,我只想躺平
"""

a = '*'
print(a*100)

abc = 'mage, jason'
#      012345678
print(abc[0])

# 列表:一次性存放多个数据(元素)

xiaomage_hobbies = ['piao','liang','jidiwangzi',150,1.60]
print(xiaomage_hobbies[2])

# 字典
xiaomage = ['height',160,'weight',
            '150','hobby',['piao','liang','jidiwangzi']]
print(xiaomage[0])
print(xiaomage[1])
print(xiaomage[2])
print(xiaomage[3])

# (key:value) 相当于一个元素
xiaomage_features = {'height':160,'weight':150,
                     'hobby':['piao','liang','jidiwangzi']}
print('*'*100)
print(xiaomage_features['height'])
print(xiaomage_features['hobby'])
