把大数据数字口语化

当出现万以上的整型数字时，经常要把它们口语化比较直观。下面分享两段代码，python与js的

python

def fn(num):
    '''
    把数字口语化
    '''
      
    ret = ''
    num = int(num)
    if num/10000 == 0:
        ret = str(num)
    else:
        if num/10**8 == 0:
            if num%10000 != 0:
                ret = str(num/10000) + '万' + str(num % 10000)
            else:
                ret = str(num/10000) + '万'
        else:
            n2 = num%10**8
            if n2%10000 != 0 and n2/10000 != 0:
                ret = str(num/10**8) + '亿' + str(n2/10000) + '万' + str(n2%10000)
            elif  n2%10000 != 0 and n2/10000 == 0:
                ret = str(num/10**8) + '亿' +  str(n2%10000)
            elif  n2%10000 == 0 and n2/10000 != 0:
                ret = str(num/10**8) + '亿' +  str(n2/10000) + '万'
            elif  n2%10000 == 0 and n2/10000 == 0:
                ret = str(num/10**8) + '亿'
    return ret
