有没有一种简单的方法来重新创建字符串，其中的变量由 `+` 连接到 python f-string？

Question

I am currently refactoring poorly written legacy code, with code snippets like this:

sql_tmp = (
                func_out
                + "(case when "
                + self.time_name
                + ">="
                + str(int(aggFrom))
                + " and "
                + segm_var
                + " = '"
                + segment
                + "'"
                + " then "
                + colName
                + " end)"
            )

or

 print(
 "Variable",
 newColName,
 "fill share <",
 str(self.min_fill_share),
 "(",
 self.nr_columns_done_print,
 "/",
 self.nr_columns_total,
 ")",
 )

I would like to have an easy way to reformat these strings into Python f-string.

AFAIK PyCharm has a way to redo "".format() type of strings into f-strings, but it does not work with pluses.

Is there an easy way to achieve this?

Answer 1

I decided to write my own script, and I paste the code snippet into long string.

"".join([
    # creating f-string variable, if the string has no " on side of it
    "{" + stripped + "}"

    if '"' not in stripped[0]

    # removing "
    else stripped.replace('"', "")
    for stripped in [
        # removing whitespace and dividing the string by '+'
        x.strip() for x in " ".join(code_snippet.split()).split("+") 
    ]
])
