Explanation: In the exercise above the code defines a function named "string_reverse()" that takes a string as input and returns its reversed version using a while loop and string manipulation. The final print statement demonstrates the result of calling the "string_reverse()" function with the...

Dictionaries maintain the order of their items in insertion order, and you can loop over them in reverse by using the reversed function, even though they're not sequences.reversed returns an iteratorThe reversed function accepts a reversible iterable, and it returns an iterator (a lazy iterable...

string x = "This is a string."; 或者int x = 5; 注意有关字符串的更多信息,请参阅本章后面的“字符串”一节。当你告诉 Pythonx = 4的时候,python“知道”了x是一个int(整数)。尽管是动态类型的,Python 是强类型的。这意味着它会抛出一个错误,而不是允许你做一些事情,比如给一个string添加一个int...
