笨方法学python 习题5

更多的变量和打印

代码如下：

print(f'''Let's talk about {my_name}.''')
print(f'''He's {my_height} inches tall.''')
print(f'''He's {my_weight} pounds heavy.''')
print(f'''Actually that's not too heavy.''')
print(f'''He's got {my_eyes} eyes and {my_hair} hair.''')
print(f'''His teeth are usually {my_teeth} depending on the coffee.''')

#this line is tricky,try to get it exactly right
total = my_age + my_height + my_weight
print(f'''If I add {my_age},{my_height},and {my_weight} I get {total}''')

输出：

Let's talk about zed A.Shaw.
He's 74 inches tall.
He's 180 pounds heavy.
Actually that's not too heavy.
He's got Blue eyes and Brown hair.
His teeth are usually White depending on the coffee.
If I add 35,74,and 180 I get 289

巩固练习

1. 将my_去掉
2. 将英寸和磅换成厘米和千克

代码如下：

name = 'zed A.Shaw'
age = 35 # not a lie
height = 74*2.54 #CM
weight = 0.454*180#KG
eyes = 'Blue'
teeth = 'White'
hair = 'Brown'


print(f'''Let's talk about {name}.''')
print(f'''He's {height} CM tall.''')
print(f'''He's {weight} KG heavy.''')
print(f'''Actually that's not too heavy.''')
print(f'''He's got {eyes} eyes and {hair} hair.''')
print(f'''His teeth are usually {teeth} depending on the coffee.''')

#this line is tricky,try to get it exactly right
total = age + height + weight
print(f'''If I add {age},{height},and {weight} I get {total}''')

输出：

Let's talk about zed A.Shaw.
He's 187.96 CM tall.
He's 81.72 KG heavy.
Actually that's not too heavy.
He's got Blue eyes and Brown hair.
His teeth are usually White depending on the coffee.
If I add 35,187.96,and 81.72 I get 304.68

Tips：

1. 变量名不可以以数字命名
2. 浮点数四舍五入，使用round()函数，入round(1.7333)
