코드

• I, V, P, Direction of I 를 입력하면 됨

# P = IV (전력 = 전압 * 전류) # V = P / I (전압 = 전력 / 전류) # I = P / V (전류 = 전력 / 전압) i, v, p, di = map(str, input("Type I, V, P, Direction of I ? ").split()) i = int(i) v = int(v) p = int(p) if i == 0: if di == '+': i = (p / v) print("The unknown Intensity of current of the node is %0.1f A" % i) elif di == '-': i = (p / v) * -1 print("The unknown Intensity of current of the node is %0.1f A" % i) if v == 0: if di == '+': v = (p / i) print("The unknown Voltage of the node is %0.1f V" % v) elif di == '-': v = (p / i) * -1 print("The unknown Voltage of the node is %0.1f V" % v) if p == 0: if di == '+': p = i*v print("The unknown Power of the node is %0.1f W" % p) elif di == '-': p = i * v * -1 print("The unknown Power of the node is %0.1f W" % p)
