print("A distância do segmento formado pelos atomos é de ", d)

TypeError: unsupported operand type(s) for -: 'str' and 'str'

Answer 1

colunas作为字符串从文件中读取，并将其拆分将产生一个字符串列表。如果您想将它们用作数字，则必须明确转换它们。 E.g：

coluna_limpa = [float(x) for x in colunas.strip().split("\t")]

Answer 2

您正在尝试减去字符串，要将字符串转换为整数，请使用int()。

d = dist(int(deltaX[0]), int(deltaX[9]),
         int(deltaY[0]), int(deltaY[9]),
         int(deltaZ[0]), int(deltaZ[9]))

或者如果您的号码是浮点数，请使用float()。

d = dist(float(deltaX[0]), float(deltaX[9]),
         float(deltaY[0]), float(deltaY[9]),
         float(deltaZ[0]), float(deltaZ[9]))
