The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Plan. Each method asks about every character of the text, and the empty text is False.
"2026".isdigit(): all digits.True."-5".isdigit(): the minus sign is not a digit.False."hello world".isalpha(): the space is not a letter.False."hello".isalpha(): all letters.True."abc123".isalnum(): letters and digits only.True."".isdigit(): there is no character, so there is no digit.False."Hello".isupper(): the letters are not all capitals.False.
Check. Run the program and compare.
Answer: True, False, False, True, True, False, False.
