用于 Mac 的 vs 代码上的基本任务的语法错误

Question

Trying to run basic code in python but coming across this currently. It might have something to do with the path at which python is located. I have added the path where python is to the settings in vs code but may have done it incorrectly.

Answer 1

The error is in line 7: greeting - 'hello, {}'.format(who_to_greet) .

You have subtracted the string 'hello, {}'.format(who_to_greet) from greeting instead of assigning it.

Change it to greeting = 'hello, {}'.format(who_to_greet) and you should be fine.

Answer 2

Your greet function is not defined on python terminal. You can execute the function from terminal and use that function or You have to exit the python terminal and run the file from the directory. Use below code to exit the python shell.

>>>exit()

After exiting. Run your python file from the terminal like below.

>python hello.py

NB You can't run function in the terminal which is in your python script. To use a function in terminal, you have to execute that function from terminal also.
