()functions return a dictionary that maps variables to their values. We can replicate that same functionality by creating a dictionary that contains variable names and their corresponding values in the form of a (key, value) pair. The following code example shows how to print variable names ...
我在行首有print,它看起来与我在单元格中的完全相同。完全意味着完全,不是有点类似。每个字符都必须匹配才能正常工作。颜色无关紧要,只有你输入的字符。 一旦它完全相同,你可以按下SHIFT-ENTER来运行代码。如果你做对了,那么你应该看到与我在本练习的你应该看到的内容部分相同的输出。如果没有,那么你做错了。不,...
