for_stmt: 'for' exprlist 'in' testlist ':' suite ['else' ':' suite] Where exprlist is the assignment target. This means that the equivalent of {exprlist} = {next_value} is executed for each item in the iterable. An interesting example that illustrates this: for i in range(4):...
Just like getting individual items out of a list, you can get individual characters out of a string using index notation. 与取得列表中的元素一样,也可以通过下标记号取得字符串中的某个字符。 类似列表,可以使用+操作符来连接(concatenate)字符串。 格式化字符串 字符串可以使用单引号或者双引号来定义。 ...

Write a Python program to implement a function that returns the count of characters whose order in the alphabet equals their index in the string. Write a Python program to use ord() and list comprehension to check if each character's position in a string corresponds to its alphabetical order...
