在Python中没有专门的char数据类型 在Python中没有switch语句。你可以使用if..elif..else语句来完成同样的工作(在某些场合,使用 字典会更加快捷。) 在C/C++中,如果你想要写for (int i = 0; i < 5; i++),那么用Python,你写成for i in range(0,5)。你 会注意到,Python的for循环更加简单、明白、不易...
1.列表元素的替换 2,多个连续的元素进行替换:利用切片 例子:对列表里的元素从大到小排序 我自己的思路(报错) pythonic的方法:直接调用sort()函数 就是如此简单(内置函数你是我的神!) 如果想从大到小排:也有内置函数!(reverse()函数) 3,列表的查找 count()函数:某个函数出现的次数 index()查找某元素的索引...

Another reason for this type of error can be the usage of an interactive shell. This type of shell only allows one statement at a time. So to avoid the SyntaxError: multiple statements found while compiling a single statement error, you can try to use semicolons in between every line. ...
