前面的步骤都对但为什么最后输入python hello.p 他不理我，又给我跳回了目录，好懵？

#1 Created at ... [Delete] [Delete and Lock User]

例如：

C:\Users\Administrator>python hello.py

C:\Users\Administrator>

#2 Created at ... [Delete] [Delete and Lock User]

确认一下文件所在路径,cd过去再用指令

#3 Created at ... [Delete] [Delete and Lock User]

或者检查一源代码有没有输出

#4 Created at ... [Delete] [Delete and Lock User]

您好，请问您这边问题解决了吗。我这里也已经是取到了正确的目录，但是输出的空值。

:\work>dir

驱动器 C 中的卷是 Windows-SSD

卷的序列号是 124E-1341

C:\work 的目录

2021/01/26 22:50 <DIR> .

2021/01/26 22:50 <DIR> ..

2021/01/26 22:50 20 hello.py

1 个文件 20 字节

2 个目录 53,366,853,632 可用字节

C:\work>more hello.py

print('hello,world')

C:\work>python hello.py

C:\work>Python hell.py

py文件直接用IDLE运行的画反而可以跑出来

如果路径对，直接输入hello.py就可以了。不用输入python hello.py
