在Python中从左右修剪指定数量的空格

def trim(text, num_of_leading, num_of_trailing):
    text = list(text)
    for i in range(num_of_leading):
        if text[i] == " ":
            text[i] = ""
        else:
            break
    for i in range(1, num_of_trailing+1):
        if text[-i] == " ":
            text[-i] = ""
        else:
            break
    return ''.join(text)
txt1 = "   Candada     "
print(trim(txt1, 1, 1))
print(trim(txt1, 2, 3))
print(trim(txt1, 6, 8))

Output:

  Candada
