使用javascript或python正则表达式，想确定数字是否为1-99，如何制作？

function isNumberBetween1And99(numberStr) {
  const regex = /^(?:[1-9]|[1-9][0-9])$/;
  return regex.test(numberStr);
}

// 测试
console.log(isNumberBetween1And99("50")); // true
console.log(isNumberBetween1And99("100")); // false
console.log(isNumberBetween1And99("0")); // false

import re

def is_number_between_1_and_99(number_str):
    regex = r'^(?:[1-9]|[1-9][0-9])$'
    return bool(re.match(regex, number_str))

# 测试
print(is_number_between_1_and_99("50"))  # True
print(is_number_between_1_and_99("100")) # False
print(is_number_between_1_and_99("0"))   # False
