如何使用python将字母转换为数字?

我有一个字典'g',我想将所有字母都转换为数字。

g = { "a" : ["c","e","h","m","k","i"],
      "b" : ["d","f","k","m"]
    }

我在堆栈溢出时发现了这一点:

def alphabet_position_Headcrab(text):
    nums = [str(ord(x) - 96) for x in text.lower() if x >= 'a' and x <= 'z']
    return " ".join(nums)

和一个喜欢的人:

def alphabet_position_wvxvw(text):
    result, i = [32, 32, 32] * len(text), 0
    for c in bytes(text.lower(), 'ascii'):
        if 97 <= c < 106:
            result[i] = c - 48
            i += 2
        elif 106 <= c < 116:
            result[i] = 49
            result[i + 1] = c - 58
            i += 3
        elif 116 <= c <= 122:
            result[i] = 50
            result[i + 1] = c - 68
            i += 3
    return bytes(result[:i-1])

但是它不适用于我的字典,而仅适用于一维字典,例如:

dic = { "a" : "g", "b" : "f"}

感谢您的帮助(也许答案很明显,但我不是编码专家)

如果函数适用于单个值,则应该可以在列表值上映射函数

new_g = {k: [alphabet_position(x) for x in v] for k, v in g.items()}

这可能对您有帮助

for key, value in g.items():
    nums = [str(ord(x) - 96) for x in value if x.lower() >= 'a' and x.lower() <= 'z']
    g[key] = nums
