#exercise2 #号的用处
#exercise3 numeric and mathematical calculations
print "Hen", 25+30/6
Print "Hen", Round (25+30/6,1) #round函数返回浮点型数据
Print section
print "Roosters", 25*3%4 #先乘法后求模

Average_passengers_per_car=passengers/cars_driven
Print "We need to put", average_passengers_per_ Car, "in each car."
#exercise5 standard text format, variables nested inside text

Print "If I add%d,%d and%d I get%d."% (My_age,my_height,my_weigh,my_age+my_height+my_weigh)

#exercise7 More Printing

#exercise8 Printing

The difference between printing "%r" and "%s" is that "%r" is good for debugging because it shows the raw data of the variable, while the other symbols are used to show the output to the user.
Formatter= "%r%r%r%r"
Print formatter% (1,2,3,4)
Print Formatter% ("one", "one", "one", "three", "four")
Print Formatter% (
"I had this ting",
"That's could type up right.",
"But it didn ' t sing.",
"So I said Goodnight.")
