for every_letter in 'Hello world': print(every_letter) 输出结果为 把for 循环所做的事情概括成一句话就是:于...其中的每一个元素,做...事情。 在关键词in后面所对应的一定是具有“可迭代的”(iterable)或者说是像列表那样的集合形态的对象,即可以连续地提供其中的每一个元素的对象。 使用for循环创建内置...
Let’s use a simple example of a for loop to illustrate how this operation works. Suppose we want to print out a list of every number between 1 and 5. We could do so using this code: for item in range(5): print(item) Our code returns: 0 1 2 3 4 In our code, we use item...

使用for循环可以遍历一个列表,从最左到最右: 1 2 3 a=["Listof some sort”] forxina: # Do something for every x 2.You can also use aforloop on a dictionary to loop through itskeyswith the following:可以使用for循环通过key值去遍历一个字典 ...

My goal is to get it to randomly generate letters and stick them together to make the length of the password, and do this until it finds the password. Every time I run it, it just makes the command prompt look like something from the Matrix. Is there something I'm doing wrong?
