字符串是非常好用的东西,所以再这个练习中你将学会如何创建包含变量内容的字符串。使用专门的格式和语法把变量的内容放到字符串里,相当于来告诉 python :“嘿,这是一个格式化字符串,把这些变量放到那几个位置。”
my_name = 'Zed A. Shaw'
my_age = 35 # not a lie
my_height = 74 # inches
my_weight = 180 # lbs
my_eyes = 'Blue'
my_teeth = 'White'
my_hair = 'Brown'
print "Let's talk about %s." % my_name
print "He's %d inches tail." % 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)
Let's talk about Zed A. Shaw. He's 74 inches tail. 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.
