通過readline()我讀取了一個包含字母和數字的txt文件。在txt文件中，第一行是 18 20 8.9354 0 0，我以這種方式讀取它import tkinter as tkfrom tkinter import filedialogroot = tk.Tk()root.withdraw()file_path = filedialog.askopenfilename()f = open(file_path)with open(file_path) as fp: first_line = fp.readline() A = first_line[1:3] B = first_line[4:6] C = first_line[7:13] D = first_line[14]問題是所有數字都是字符串，如果我嘗試這樣做，A+B我會得到1820而不是40如何在本地修復它（僅適用于實際包含數字的行）？非常感謝

我將在此處使用字符串拆分以及列表理解來將每個字符串數字映射到真正的浮點數：
with open(file_path) as fp:
first_line = fp.readline()
nums = first_line.split(' ')
results = [float(i) for i in nums]
A = results[0]
B = results[1]
C = results[2]
D = results[3]
