As found in PriP 1.2, Data HandlingClass 12 Computer Science with Python by Sumita Arora is referred to in schools affiliated to but not limited to CBSE.

Q10. Given the following Boolean variables, what would be the output of the following statements?

x = True
y = False
z = False
  1. print(not x or y)
    not x → not True → False
    y → False
    Therefore, not x or y → False or False → False
    OutputFalse
  2. print(not x or not y and z)
    not x → not True → False
    not y → not False → True
    z → False
    Now evaluate not y and z → True and False → False
    Therefore, not x or (not y and z) → False or False → False
    OutputFalse
  3. print(not x or y or not y and x)
    not x → not True → False
    y → False
    not y → not False → True
    x → True
    Now evaluate not y and x → True and True → True
    Therefore, not x or y or (not y and x) → False or False or True → True
    OutputTrue
  4. print('ant' < 'amoeba')
    The first character of both strings is 'a', which is the same. The second character of 'ant' is 'n', and the second character of 'amoeba' is 'm'.
    Since 'n' has a higher ASCII value than 'm''ant' is considered greater than 'amoeba'.
    Therefore, the expression evaluates to False.
    OutputFalse

This statement compares two strings lexicographically, or in the way of dictionaries. So, in a lexicographic order, the comparison is done character by character based on their ASCII values.

Basically, you compare which word comes first like in a dictionary. So amoeba would come first in a dictionary between the two.
