  print("True")

Example  2.    (From User)

a=int(input("Enter the first number:"))

b=int(input("Enter the second number:"))

if (a<b):

  print("True")

a=10

b=10

c=30

d=10

if ((a==b) and (c==d)):

 print("Condition True")

else:

 print("Condition is Fals") 

 

 Example 2.

a=10

b=10

c=30

d=30

if ((a==b) or (c==d)):
