从列表中删除特定字符

Question

我想知道 Python 库是否有内置函数可以从列表中删除特定字符？

EG:

在这种情况下，我想从列表中删除所有零，我该怎么做。

[76499618373903541704700923371133789862262100000000000000000000000]

注意：此列表只有 1 个值

Answer 1

要除以10，只要能被10整除即可：

def remove_zeros(number):
    while number and number % 10 == 0:
        number //= 10
    return number

number_in_a_list = [764996183739035417047009233711337898622621000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000]

result = [remove_zeros(n) for n in number_in_a_list]

Answer 2

最简单的方法是将其转换为字符串并去掉最后一个零：

nums =[7649900000000000000]
result = [int(str(n).rstrip('0')) for n in nums]
print result  # You will get: [76499]

Answer 3

>>> f = lambda n: n % 10 ==0 and f(n//10) or n
>>> f(764996183739035417047009233711337898622621000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000)
