Original string: reverse Reverse string: esrever Explanation: In the exercise above the code demonstrates the use of a "reverse()" function that utilizes slicing ([::-1]) to reverse a given input iterable. It then applies this function to reverse both the string '1234abcd' and the string 'reverse' and prints the...

You can also reverse a string in Python by using a for loop to iterate over the characters in the string and append them to a new string in reverse order. Here’s an example: # Using a for loop to reverse a string my_string = 'Hello, World!' reversed_string = '' for char in...

但首先,让我们看一些列表和字符串方法。 reverse()和 append()列表方法 列表数据类型有一些您可能经常使用的方法:reverse()和append()。reverse()方法将颠倒列表中项目的顺序。尝试输入spam = [1, 2, 3, 4, 5, 6, 'meow', 'woof'],然后输入spam.reverse()以颠倒列表。然后输入spam以查看变量的内容。
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...
Fizz Buzz - Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”. Reverse a String - Enter a str...
Python语言采用严格的缩进来表示程序逻辑。也就是我们所说的Python程序间的包含与层次关系。一般代码不要求缩进,顶行编写且不留空白。在if、while、for、def、class等保留字所在完整语句后通过英文的“:”结尾并在之后行进行缩进,表明后续代码与紧邻无缩进语句的所属关系。
