这里statement1和statement2两个变量都为字符串,但是quantity这个变量为整数,因此print statement1 + quantity + statement2会报错TypeError: cannot concatenate 'str' and 'int' objects, 提示不能将字符串和整数拼接合并。解决的办法是使用str()这个函数将quantity从整数转化为字符串,举例如下: ...

由于python3.x系列不再有 raw_input函数,3.x中 input 和从前的 raw_input 等效,把raw_input换成input即可。 SyntaxError: multiple statements found while compiling a single statement 这是因为整体复制过去运行而产生的错误;解决方案如下: 方法一:先将第一行复制,敲一下回车,再将剩下的部分复制过去,运行; ...

print(str2.startswith('DA')) # True find(str, beg=0, end=len(string))检测str是否包含在字符串中,如果指定范围beg和end,则检查是否包含在指定范围内,如果包含,返回开始的索引值,否则返回 -1。 rfind(str, beg=0,end=len(string))类似于find()函数,不过是从右边开始查找。
