How to execute python function in vsc terminal
问题
def add(a,b):
return a+b
我在VSC中创建了一个Python函数，我想在终端中执行它，像这样：
add(2,3)
但是这样会出现一个错误，类似于bash: 附近的语法错误 2,3。
我认为问题出在终端的路径，但我不知道该怎么做。
我尝试了一些与终端路径相关的操作，但我不知道问题出在哪里。
英文:
def add(a,b):
return a+b
I made python function at vsc and I want to execute that function in terminal like
add(2,3)
But if so there is an error like bash: syntax error near unexpected token `2,3'
I think the matter of path of terminal but I do not know what to do
I have tried something related to path of terminal but IDK what is matter

You need to save the file with the function, then run the function through the command line using python3 -c.
I created a file sample.py with your function:
def add(a,b):
return a+b
and I ran the following command from the command-line terminal:
python3 -c 'from sample import add; print(add(2,3))';
and the output was:

Note that, I am using Linux, that's why it is python3, for Windows, you need to use python only.

如果你想经常从命令行运行你的函数，可能最清晰的方式是将它制作成一个可执行脚本。在Linux上：
#!/usr/bin/python3
from sys import argv
def add(a, b):
return a + b
if __name__ == '__main__':
print(add(int(argv[1]), int(argv[2])))
确保脚本是可执行的：
chmod +x add.py
现在你可以从终端运行它：
./add.py 2 3

如果你打算使它更复杂，我建议查看argparse。它比argv更强大。
英文:
If you want to run your function from the command line a lot, it may be cleanest to make it an executable script. On Linux:
#!/usr/bin/python3
from sys import argv
def add(a, b):
return a + b
if __name__ == '__main__':
print(add(int(argv[1]), int(argv[2])))
Make sure the script is executable:
chmod +x add.py
Now you can run it from the terminal:
./add.py 2 3

If you are going to make it more complex, I recommend checking out argparse. It's more powerful than argv.

-
你需要先打开 Python 终端
-
定义函数
-
然后执行函数
你也可以在脚本文件中选择部分代码，然后使用<kbd>Shift</kbd>+<kbd>Enter</kbd>打开 Python 交互终端并执行代码。
你可以详细阅读Python 交互窗口。
另外，使用Jupyter Notebooks可能更方便。
英文:
-
You need to open the python terminal first
-
Define the function
-
Then execution function
You can also select part of the code in the script file, and then use <kbd>Shift</kbd>+<kbd>Enter</kbd> to open the python interactive terminal and execute the code.
You can read Python Interactive window in detail.
In addition, it may be more convenient to use Jupyter Notebooks.
