You could also use 'r' before your path reference OR use '/' to avoid the need for '\'

For example: r"C:\Users\Admin\Desktop\Data\"



Programming languages, such as Python, treat a backslash () as an escape character. For instance, \n represents a line feed, and \t represents a tab. When specifying a path, a forward slash (/) can be used in place of a backslash. Two backslashes can be used instead of one to avoid a syntax error. A string literal can also be used by placing the letter r before a string containing a backslash so it is interpreted correctly.

    r"C:\Users\Admin\Desktop\Data\" raises a SyntaxError, so it actually needs to be r"C:\Users\Admin\Desktop\Data\""
