Logic Gates in Python
In this article, we will learn about Logic Gates in Python. Let’s look at each of the logic gates in Python in detail with some easy examples.
All of us are quite familiar while implementing logic gates in the processing of electrical signals and are widely used in the electrical and electronics industry. They are used in the diodes and transistors so that we can design by proper alignment of these electronic devices. In this article we will learn about the implementation of some basic gates ‘and‘, ‘or‘ ,’not‘ , ‘nand‘ ,’nor‘ in Python 3.x or earlier.
These gates can be implemented by using user-defined functions designed in accordance with that of the truth table associated with the respective gate.
Construction of And Gate in Python
Example
def AND (a, b):
if a == 1 and b == 1:
return True
else:
return False
# main function
if __name__=='__main__':
print(AND(0,0))
print(AND(1,0))
print(AND(0,1))
print(AND(1,1))
Output
False
False
False
True
Construction of Or Gate in Python
Example
def OR(a, b):
if a == 1:
return True
elif b == 1:
return True
else:
return False
# main function
if __name__=='__main__':
print(OR(0,0))
print(OR(1,0))
print(OR(0,1))
print(OR(1,1))
OUTPUT
False
True
True
True
Construction of Not Gate in Python
Example
def NOT(a):
if(a == 0):
return 1
elif(a == 1):
return 0
# main function
if __name__=='__main__':
print(OR(0))
print(OR(1))
Output
True
False
Construction of Nand Gate in Python
Example
def NAND (a, b):
if a == 1 and b == 1:
return False
else:
return True
# main function
if __name__=='__main__':
print(NAND(0,0))
print(NAND(1,0))
print(NAND(0,1))
print(NAND(1,1))
Output
True
True
True
False
Construction of Nor Gate in Python
Example
def NOR(a, b):
if(a == 0) and (b == 0):
return True
elif(a == 0) and (b == 1):
return False
elif(a == 1) and (b == 0):
return False
elif(a == 1) and (b == 1):
return False
# main function
if __name__=='__main__':
print(NOR(0,0))
print(NOR(1,0))
print(NOR(0,1))
print(NOR(1,1))
Output
True
False
False
False
Conclusion
In this article, we learned how to implement logic gates in Python 3.x. Or
earlier. We also learned about two universal gates i.e. NAND and NOR gates.
