Python implementation outputs a number in reverse order of specified requirements

This article mainly describes the python implementation of the specified requirements in reverse order to output a number of methods, involving Python for string traversal, judgment, output and other related operations skills, the need for friends can refer to the following

This example describes how Python implements a method of outputting a number in reverse order to the specified requirements. Share to everyone for your reference, as follows:

The problem is : Enter a number, follow the specified requirements to output the number in reverse, very simple, the following is the implementation:

#!usr/bin/env python#encoding:utf-8 "" __author__: Yishui Cold city Function: Reverse output A number if the number is a positive direct output such as: 177---> 771 if the number is negative, keep the minus sign, such as: -945--->-549 if the number is reversed with 0 results after 0 such as:--->1 if the number is very general cause overflow return 0 can be "def inverse_num (one_num):  " "  Reverse output a number"  if one_num>99999999:    return 0  elif one_num==0:    return 0  else:    If one_num>0:      flag=true    Else:      flag=false      one_num*=-1    one_num_list=list (str (one_num)) While    one_num_list[-1]== ' 0 ':      one_num_list.pop ()    tmp= ". Join (One_num_list[::-1])    if flag:      return tmp    else:      return '-' +tmpif __name__ = = ' __main__ ':  print "script home test Result:"  one_num_list=[ 124,-345,1000,999999999,0]  for one_num in one_num_list:    print One_num, Inverse_num (one_num)

The results are as follows:

Python implements a method of entering multiple lines in idle
