python - Why do these two command give different outputs? -


command 1:

subprocess.call(["echo","\"hw\""])

output:

"hw"

command2 :

subprocess.call(["echo","""hw"""])

output:

hw

your first command passes quotes echo system command, , equivalent doing on command line:

$ echo "hw"

your second command passes hw string (no quotes) echo , equivalent following:

$ echo hw

in second command, you're using docstring notation strings, equivalent "hw" 'hw'.
