I have a python script that looks like this:
a='{}'
From my cmdline i want to be able to pass a parameter for that value in the brackets. So:
python- my_script.py Hello World
The output would then be:
'Hello World'
Any ideas or suggestion as to how to pass a parameter on the command line in a python script when running it? I am new to python so any tips would help!
Reference here !
I'm also fairly new to Python so not 100% positive this works but assuming it does, To recreate what your searching for.
#!/usr/bin/python
import sys
print ('Number of arguments:', len(sys.argv), 'arguments.')
print ('Argument List:', str(sys.argv))
After adding the Import sys
Where your python my_script.py 'Hello World'
Note that:
my_script.py
equals sys.argv[0]
'Hello World'
equals sys.argv[1]
Therefore setting a = sys.argv[1]
should work!
To test it try to print(a)
Also note that this will not work if your cmdline is python my_script.py Hello World
This will treat Hello and world as two separate arguments.
