On a side note, if you haven't run into problems already, you likely will with how paths are being defined. In the posted script, in-memory paths are being defined using single backslashes. In Python, backslashes are escape characters:
2.4.1. String literals ¶
....
In plain English: String literals can be enclosed in matching single quotes (') or double quotes ("). They can also be enclosed in matching groups of three single or double quotes (these are generally referred to as triple-quoted strings). The backslash (\) character is used to escape characters that otherwise have a special meaning, such as newline, backslash itself, or the quote character. String literals may optionally be prefixed with a letter 'r' or 'R'; such strings are called raw strings and use different rules for interpreting backslash escape sequences. A prefix of 'u' or 'U' makes the string a Unicode string. Unicode strings use the Unicode character set as defined by the Unicode Consortium and ISO 10646. Some additional escape sequences, described below, are available in Unicode strings. A prefix of 'b' or 'B' is ignored in Python 2; it indicates that the literal should become a bytes literal in Python 3 (e.g. when code is automatically converted with 2to3). A'u' or 'b' prefix may be followed by an 'r' prefix.
In triple-quoted strings, unescaped newlines and quotes are allowed (and are retained), except that three unescaped quotes in a row terminate the string. (A “quote” is the character used to open the string, i.e. either ' or ".)
Unless an 'r' or 'R' prefix is present, escape sequences in strings are interpreted according to rules similar to those used by Standard C. The recognized escape sequences are:
| Escape Sequence | Meaning | Notes |
|---|
\newline | Ignored | |
\\ | Backslash (\) | |
\' | Single quote (') | |
\" | Double quote (") | |
.... | .... | |
Also, I don't think the script is doing what you think it is doing with regard to the Make Feature Layer tool. The second argument of the Make Feature Layer tool is the "name of the feature layer to be created," just a name, not a path. On Line 02, you aren't actually storing the feature layer in-memory, you are simply creating a feature layer with "In_memory" as part of its name. Although taking such an approach works, it is bound to cause confusion using names that resemble paths when in fact they aren't paths.
