我有一個程式可以計算特定公式的測量值。結果應顯示在控制臺和一行解決方案上。不幸的是，當我運行這個程式時，錯誤發生了。我嘗試使用，zip()但沒有幫助。
這是回溯錯誤：
File "W:/Labaratorni/micro/main.py", line 34, in main
print(f'T[C] = {temperature - 273.15:.2f} \t R = {resistance:.3f}')
TypeError: unsupported format string passed to NoneType.__format__
這是我的代碼：
import numpy as np
K = 273.15
T = [1.4, 25, 72]
R = [3440, 1175, 453]
def make_solve(temperature_kalvin: float, temperatures: list, resistances: list):
matrix_a = []
for element in R:
matrix_a.append([1, np.log(element), pow(np.log(element), 3)])
matrix_b = np.array([1 / (t K) for t in T])
solve = np.linalg.solve(np.array(matrix_a), matrix_b)
return solve
def resistance_from_temperature(temperature: float, parameter_a: float, parameter_b: float,
parameter_c: float):
x = 1 / parameter_c * (parameter_a - 1 / temperature)
y = pow((pow((parameter_b / (3 * parameter_c)), 3) pow(x / 2, 2)), .5)
result = np.exp((y - x / 2) ** (1 / 3) - (y x / 2) ** (1 / 3)) / 7.3
def get_list_of_second_parameters():
solves = make_solve(K, T, R)
temperatures = np.linspace(0 K, 100 K, 101)
resistances = [resistance_from_temperature(temperature, solves[0], solves[1], solves[2]) for temperature in temperatures]
return temperatures, resistances
def main():
temperatures, resistances = get_list_of_second_parameters()
for temperature, resistance in zip(temperatures, resistances):
print(f'T[C] = {temperature - 273.15:.2f} \t R = {resistance:.3f}')
input()
main()
uj5u.com熱心網友回復：
在這種情況下，阻力是回傳 Nan，但問題出在這條線上
y = pow((pow((parameter_b / (3 * parameter_c)), 3) pow(x / 2, 2)), .5)
它不是在計算 y 的值。
另一個問題resistance_from_temperature 沒有回傳結果的值。
