a.sort()
print (a)
您需要将列表转换为浮点列表，而不是字符串
a = [*map(float, a)] # [*map(float, a)] is equivalent to list(map(float, a))
a.sort()
print(a)
应该管用。
如果要将其转换回 str ，可以执行以下操作：
a = [*map(str,a)]
或者，如果您不想要尾随零：
a = [*map(lambda c: str(round(c,2)).rstrip('0').rstrip('.'), a)]
正如 ShadowRanger 所指出的，如果您希望它保留在 str 中而不在任何时候将其转换为 Float，您可以这样做
a.sort(key = float)
或者
a = a.sorted(key = float)
