原创笨办法22到目前为止你学到了什么？

结果之前学的内容，写了一小段from sys import argvscript, filename1, filename2 = argvdef add(a, b, c): return a + b + cdef rewind(f): f.seek(0)file1 = open(filename1, 'w')plus = add("\t 12345 \n", "I'll play

原创笨办法21函数的返回值

代码如下：把第3行的加号换成了减号def add(a, b): print "ADDING %d + %d" % (a, b) return a - bdef substract(a, b): print "SUBTRACTING %d - %d" % (a, b) return a - bdef multiply(a, b): print "MULTIP

原创笨办法20函数和文件

代码如下，在打印了第一行之后，多加入了一次函数seek()的操作：#coding:utf-8from sys import argvscript, input_file = argvdef print_all(f): # 打印从文件中读取的内容 print f.read() def rewind(f): # 将文件内部的指针重新指向开头 f.seek(0) def print_a_l

原创笨办法18命名、变量、代码、函数

源代码如下：#coding: utf-8# this one is like your scripts with argvdef print_two(*args): arg1, arg2 = args print "arg1: %r, arg2: %r" % (arg1, arg2)# ok, that *args is actually pointless, we can ju

原创笨办法17更多文件操作

源代码如下from sys import argvfrom os.path import existsscript, from_file, to_file = argvprint "Copying from %s to %s" % (from_file, to_file)# We could do these two on one line too, how?input = open(from_

原创笨办法16读写文件

代码如下：#coding:utf-8from sys import argvscript, filename = argvprint "We're going to erase %r." %filename #提示语句，告知用户将抹掉文件print "If you don't want that, hit CTRL-C (^C)." #提示语句，停止操作的按键print "If you do

原创笨办法15读取文件

代码如下：#coding:utf-8from sys import argv script, filename = argv txt = open(filename) #将打开的文件内容赋值给变量txtprint "Here's your file %r:" % filename print txt.read() #读取txt的内容print "Type the filename again:"

原创笨办法14提示和传递

加分习题: 2. 将 prompt 变量改成完全不同的内容再运行一遍：将‘>’换成“please enter:” 3. 给你的脚本再添加一个参数，让你的程序用到这个参数：加入参数，dear以下为代码：from sys import argvscript, user_name, nike_name = argvprompt = "please enter: "print "Hi %s%s, I'

原创笨办法13参数、解包、变量_草稿

加分习题3：将 raw_input 和 argv 一起使用，让你的脚本从用户手上得到更多的输入。from sys import argvscript, first, second, third = argv'''print "The script is called:", scriptprint "Your first variable is:", firstprint "Your seco

原创笨办法12提示别人

老样子，把源代码乱改了一通：age = input("How od are you? ")height = raw_input("How tall are you? "), ("what?"), raw_input("again ")weight = raw_input("How much do you weight? ")print "So,you're %r old, %r tall and

原创笨办法11提问-raw_input

好气啊，写完了没发表，跑去改之前的一篇，结果把这篇顶掉了啊！说好的重新加载就恢复呢！？呢？！好气好气，，，源代码如下，有个改动print "How old are you?",age = raw_input()print "How tall are you?",height = raw_input()print "How much do you weigh?",weigh = raw_in
