这个习题涉及写两个文件：一个是正常的ex15.py文件，另外一个是ex15_sample.txt下面是该文本内容： This is stuff I typed into a file. It is really cool stuff. Lots and lots of fun to have in here. 一：代码 from sys import argv script, file

一：代码 from sys import argv script, user_name = argv prompt = '> ' print "Hi %s, I'm the %s script." % (user_name, script) print "I'd like to ask you a few questions." print "Do you like me %s?" % us

一：代码 print "How old are you?", age = raw_input() print "How tall are you??", height = raw_input() print "How much do you weigh?", weight = raw_input() print "So, you're %r old, %r tall and %r heavy.

一：代码 # _*_ coding:utf-8 _*_ tabby_cat = "\tI'm tabbed in." # \t水平制表符 persian_cat = "I'm split\non a line." # \n 换行符 backslash_cat = "I'm \\ a \\ cat." fat_cat = """ I'll do a list: \t* Cat food \t*

一：代码 # Here's some new strange stuff, remember type it exactly. days = "Mon Tue Wed Thu Fri Sat Sun" months = "Jan\nFed\nMar\nApr\nMay\nJun\nJul\nAug" print "Here are the days: ",days print "Here a

一：代码 from sys import argv script, first, second, third = argv print "The script is called:", script print "Your first variable is:", first print "Your second variable is:", second print "Your third

一：代码 print "Mary had a little lamb." print "Its fleece was white as %s." % 'snow' print "And everywhere that Mary went." print "." * 10 # what'd that do? end1 = "C" end2 = "h" end3 = "e" end4 = "e"

一：代码 x = "There are %d types of people." % 10 binary = "binary" do_not = "don't" y = "Those who know %s and those who %s" % (binary, do_not) print x print y print "I said: %r." % x print "I also sa

一：代码 cars = 100 space_in_a_car = 4.0 drivers = 30 passengers = 90 cars_not_driven = cars - drivers cars_driven = drivers carpool_capacity = cars_driven * space_in_a_car average_passengers_per_car = p

一：代码 print "I will now count my chickens:" print "Hens", 25 + 30 / 6 print "Rooters", 100 - 25 * 3 % 4 print "Now I will count the eggs:" print 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6 print "Is it true

一：代码： # A comment, this is so you can read your program later. # Anything after the # is ignored by python. print "I could have code like this." # and the comment after is ignored # You can also us

对于raw_input()而言，你可以让它显示出一个提示，从而告诉别人应该输入什么。 一：代码 age = raw_input("How old are you? ") height = raw_input("How tall are you? ") weight = raw_input("How much do you weight? ") print "So, you're %r old
