shebang-not-first-line (EXE005)#

Derived from the flake8-executable linter.

What it does#

Checks for a shebang directive that is not at the beginning of the file.

Why is this bad?#

In Python, a shebang (also known as a hashbang) is the first line of a script, which specifies the interpreter that should be used to run the script.

The shebang's #! prefix must be the first two characters of a file. If the shebang is not at the beginning of the file, it will be ignored, which is likely a mistake.


foo = 1
#!/usr/bin/env python3

Use instead:

#!/usr/bin/env python3
foo = 1
