Question

How to execute Python multi-line statements in the one-line at command-line?

Answer 1

There are multiple ways in which you can use multiline statements in the command line in python. For example, bash supports multiline statements, which you can use like:

$ python -c ' > a = True > if a: > print("a is true") > '

This will give the output:

a is true

If you prefer to have the python statement in a single line, you can use the \n newline between the commands.

For example,

$ python -c $'a = True\nif a: print("a is true");'

This will give the output:

a is true
