如何在一个字符串中去除开头和结尾的零？Python

我有几个类似的字母数字字符串，如下所示：

listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', '000alphanumeric']

去除尾部零后的期望输出为：

listOfNum = ['000231512-n','1209123100000-n','alphanumeric', '000alphanumeric']

去除前导零后的期望输出为：

listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric']

去除前导和尾部零后的期望输出为：

listOfNum = ['231512-n','1209123100000-n', 'alphanumeric', 'alphanumeric']

目前我是这样做的，请提供更好的方法：

listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', \
'000alphanumeric']
trailingremoved = []
leadingremoved = []
bothremoved = []
# 去除尾部零
for i in listOfNum:
  while i[-1] == "0":
    i = i[:-1]
  trailingremoved.append(i)
# 去除前导零
for i in listOfNum:
  while i[0] == "0":
    i = i[1:]
  leadingremoved.append(i)
# 去除前导和尾部零
for i in listOfNum:
  while i[0] == "0":
    i = i[1:]
  while i[-1] == "0":
    i = i[:-1]
  bothremoved.append(i)
