Logical operators are similar to Boolean expressions that return a boolean result.
These operators are called binary because they acquire two operands.

Operator Meaning

AND Both sides must be true
OR One one the two conditions must be true

XOR One side or other must be true but not both
NOT Negates truth

5.9. Looping Statement in Python

A For loop is used for repeating over a sequence (that is either a list or a string). This

is less like the FOR keyword in other programming languages and works more like an
iterator method as found in other object-orientated programming languages.

For example, we have a list of students and we want to display the student with the
highest marks without using the max() function:

Sample code:

# This defines a list of student marks
stdMarks = [70, 80, 92.5, 60.2]
# This variable keeps track of the max marks

maxMarks = 0

# for loop block
for i in range(0,4):
if stdMarks[i] > maxMarks:

maxMarks = stdMarks[i]

# Prints highest student marks
print(“Highest student marks are:”, maxMarks)
