Anomalous backslash in string: '\ '. String constant might be missing an r prefix.

Description
Backslash is present in the literal string but is not a valid escape sequence. If it is intended to be an escape sequence, use the correct escape characters. If it is intended to be a literal backslash, it can either be replaced with with an escaped backslash \\, or you can add an r prefix to make it a "raw" string.
Bad practice
filepath = "C:\myfiles\run.py"
Recommended
filepath = "C:\\myfiles\\run.py" # use `\\` to render one backslash
filepath = r"C:\myfiles\run.py" # use the `r` prefix to avoid unnecessary escapes
