I'm going to actually use Python to do this.And this is also an example of how just a really simple task in your life,you can use computers or programming to do that.Because if I choose a random number,I might be biased because,for ...
# simple.for.pyfornumberin[0,1,2,3,4]:print(number) 当执行时,这段简单的代码打印出从0到4的所有数字。for循环接收列表[0, 1, 2, 3, 4],在每次迭代时,number从序列中获得一个值(按顺序迭代),然后执行循环体(打印行)。number的值在每次迭代时都会改变,根据序列中接下来的值。当序列耗尽时,for循环...
As well as being a useful interactive interface to Python, IPython also provides a number of useful syntactic additions to the language; we’ll cover the most useful of these additions here. In addition, IPython is closely tied with theJupyter project, which provides a browser-based notebook t...

The name main is not a Python keyword, so it could have been called anything. Having a main function of some sort isn’t required. For short programs (typically less than one page of code), I usually dispense with a main function and just start with executable statements. Next, the ...

for square in squares: print(square) 平方操作和生成新列表的过程都浓缩进了一行代码。你是不是已经晕头转向了,让我们来看看这行代码发生了什么。 首先我们定义了一个列表,名字为 squares。 接下来看看列表中括号中的代码: for number in range(1, 11) 它在1-10之间创建一个循环,把每个数字存储到变量 ...
