I think this function can be done in one line, something like: return name + str([space + "_idx" for space in space_list])

function_str += PYTHON_FILE_TAB + "t2 = t2oovv.transpose(2, 3, 0, 1)\n\n"

Line is too long, there shouldn't be spaces around the = signs in the function definition.

This else is unnecessary, you can just have an unintended return after the the if statement
