Today I written a calculator program to calculate the ohms formula by python programming language...

If you found better way to write it again please let me know directly message me or comment me.

# here program starts.

print ("""ohms calculator v1.0

""")

print("""Please enter only numbers unless it will show you an error

""")

print("""Enter minimum 2 values

""")

v=input(str('[Enter value of V]: '))

i=input(str('[Enter value of I]: '))

r=input(str('[Enter value of R]: '))

op=input(str("""[Enter 1 to calculate voltage]

[Enter 2 to calculate Ampere]

[Enter 3 to calculate Resistance]

"""))

if op=='1':

print(int(i)*int(r))

elif op=='2':

print(int(v)/int(r))

elif op=='3':

print(int(v)/int(i))

This is a very good start. I can see that there would be a problem if I entered a resistance of 0 then selected to calculate the voltage. There should be a try/catch or division by zero verification.
