TypeError: Not All Arguments Converted During String Formatting Resolved

When attempting to format a string using placeholders like {0} with the % formatting operator, you may encounter a "TypeError: not all arguments converted during string formatting" error. This error indicates an inconsistency in the formatting style you are using.

The solution lies in using the correct string formatting operator. In your case, you are using % formatting but attempting to substitute placeholders with the .format method, which is incompatible. To resolve this issue, you should either use the % formatting operator consistently or switch to using the .format method.

If you choose to stay with % formatting, here's an example:

<code class="python">print("&quot;'%s' is longer than '%s'&quot; % (name1, name2))  # Correct use of % formatting</code>

However, using the .format method is the preferred approach:

<code class="python">print("'{0}' is longer than '{1}'".format(name1, name2))  # Correct use of .format</code>

Remember, the .format method requires the placeholders to be enclosed in curly braces {} and the values to be passed as arguments to the method.
