#coding=utf-8
#1. 将字符串 "abcd" 转成大写
#2. 计算字符串 "cd" 在 字符串 "abcd"中出现的位置
#3. 字符串 "a,b,c,d" ，请用逗号分割字符串，分割后的结果是什么类型的？
#4. "{name}喜欢{fruit}".format(name="李雷") 执行会出错，请修改代码让其正确执行
#5. string = "Python is good", 请将字符串里的Python替换成 python,并输出替换后的结果
#6. 有一个字符串 string =  "python修炼第一期.html"，请写程序从这个字符串里获得.html前面的部分，要用尽可能多的方式来做这个事情
#7. 如何获取字符串的长度？
#8. "this is a book",请将字符串里的book替换成apple
#9. "this is a book", 请用程序判断该字符串是否以this开头

#12. "This IS a book"， 请将字符串里的小写字符，转成大写字符
#13. "this is a book\n"， 字符串的末尾有一个回车符，请将其删除
print "abcd".upper();
print "abcd".count("cd");
print "a,b,c,d".split(",") #得到一个元素是字符的列表
print "{name}喜欢{fruit}".format(name="李雷", fruit='苹果')
print "Python is good".replace("Python","python");
print "python修炼第一期.html"[0:-5];
print  "7题：", len("abc");
print  "8题:","this is a book".replace("book","apple");
print  "9题:","this is a book".startswith("this");
print  "10题:","this is a book".endswith("apple");
print  "11题:","This IS a book".lower();
print  "12题:","This IS a book".upper();
print  "13题:","this is a book\n".rstrip("\n");
print  "13题:","this is a book\n".strip("\n");

运行结果如下：

ABCD
1
['a', 'b', 'c', 'd']
李雷喜欢苹果
python is good
python修炼第一期
