Use logical operators to combine two conditional expressions into one while loop in Python. In the same way, you can use Multiple condition expressions in a while loop.
For example while 2 conditions in Python
Simple example code combines multiple conditional expressions in a while loop. We will do use or and make a while loop with multiple conditions.
Logical AND “&” Operator
while True and True: #Will run
while True and False: #Won't run
while False and True: #Won't run
while False and False: #Won't run
The and the operator says to evaluate them separately and then consider their results as a whole. If (and only if) both A and B are true, then the loop body will execute.
a = 5
b = 10
count = 0
while count < a and count < b:
print("Count", count)
count += 1
Output:
Logical OR “| |”Operator
while True or True: #Will run
while True or False: #Will run
while False or True: #Will run
while False or False: #Won't run
The or the operator says to evaluate them separately and then consider their results as a whole. Now, however, the loop body will execute if at least one of the conditional expressions is true.
a = 5
b = 10
count = 0
while count < a or count < b:
print("Count", count)
count += 1
Output:
Count 0
Count 1
Count 2
Count 3
Count 4
Count 5
Count 6
Count 7
Count 8
Count 9
