格式化方法:
%c 格式化字符及其ASCII码 %s 格式化字符串 %d 格式化整数 %u 格式化无符号整型 %o 格式化无符号八进制数 %x 格式化无符号十六进制数 %X 格式化无符号十六进制数(大写) %f 格式化浮点数字,可指定小数点后的精度 %e 用科学计数法格式化浮点数 %E 作用同%e,用科学计数法格式化浮点数 %g %f和%e的简写 %G %f 和 %E 的简写 %p 用十六进制数格式化变量的地址

 

print("习题5:更多变量和打印!!!")

my_name = jiajie.zheng
my_age = 27
my_height = 173 #cm
my_weight = 120 #G
my_eyes = black
my_teeth = white
my_hair = black

#  %s 表示格式化字符串
print("Let‘s talk about %s." %my_name)

# %d 表示格式化数字
print("He‘s %d inches tall." %my_height)
print("He‘s %d pounds heavy."%my_weight)
print("Actually that‘s not too heavy.")
print("He‘s got %s eyes and %s hair."%(my_eyes,my_hair))
print("His teeth are usually %s depending on the coffee." %my_teeth)

#this line is tricky,try to get it exactly right
print("If I add %d,%d,and %d I get %d." %(my_age,my_height,my_weight,my_age + my_height + my_weight))



print("以下为加分题:1、去掉所有的my_")
name = jiajie.zheng
age = 27
height = 173 #cm
weight = 120 #G
eyes = black
teeth = white
hair = black

#  %s 表示格式化字符串
print("Let‘s talk about %s." %name)

# %d 表示格式化数字
print("He‘s %d inches tall." %height)
print("He‘s %d pounds heavy."%weight)
print("Actually that‘s not too heavy.")
print("He‘s got %s eyes and %s hair."%(eyes,hair))
print("His teeth are usually %s depending on the coffee." %teeth)

#this line is tricky,try to get it exactly right
print("If I add %d,%d,and %d I get %d." %(age,height,weight,age + height + weight))

print("以下为加分题:2、使用更多的格式化字符,%r:不管什么都打印出来")
name = jiajie.zheng
age = 27
height = 173 #cm
weight = 120 #G
eyes = black
teeth = white
hair = black

#  %s 表示格式化字符串
print("Let‘s talk about %s." %name)

# %d 表示格式化数字
print("He‘s %r inches tall." %height)
print("He‘s %r pounds heavy."%weight)
print("Actually that‘s not too heavy.")
print("He‘s got %r eyes and %r hair."%(eyes,hair))
print("His teeth are usually %r depending on the coffee." %teeth)

#this line is tricky,try to get it exactly right
print("If I add %r,%r,and %r I get %r." %(age,height,weight,age + height + weight))
