s = 'madam'All of the following expressions produce the same result except one. Which one?

To analyze the question, let's break it down into manageable parts.

1. Break Down the Problem

We want to identify which expression involving the string s = 'madam' does not yield the same result as the others. We need to compare various expressions that can be generated using s.

2. Relevant Concepts

Common string expressions that might be considered include:

• s == s[::-1] (checks if the string is a palindrome)
• s.lower() == s[::-1].lower() (checks palindrome ignoring case)
• s[::-1] (reverses the string)
• Boolean checks such as converting to a boolean or comparing lengths.

3. Analysis and Detail

Let's analyze possible expressions:

1. s == s[::-1]: This compares the string with its reverse. For s = 'madam', this will return True.
2. s.lower() == s[::-1].lower(): Since 'madam' is the same in lowercase, this will also return True.
3. s[::-1]: This will produce 'madam', the reversed string.
4. len(s) == 5: This just checks the length of the string, which is a numerical comparison.

4. Verify and Summarize

• For expressions 1 and 2, the results are True.
• Expression 3 gives 'madam', a string.
• Expression 4 gives 5, an integer.

Thus, expressions 1 and 2 yield True, expression 3 yields 'madam', and expression 4 yields 5.

Final Answer

The expression that does not produce the same result as the others is: s[::-1] (as it produces a string instead of a boolean result).
