Take input number from the user and print its reverse.

從用戶處獲取輸入號(hào)碼并打印其反面。

Example:

例：

Input:12345Output:54321

Here, we are implementing program to reversing a given number using 2 different ways.

在這里，我們正在實(shí)施程序，以使用2種不同的方式來(lái)反轉(zhuǎn)給定的數(shù)字 。

1) Famous approach for reversing the number: Take input from the user and typecast into an integer, then iterate in the loop till num is not become zero, inside the loop:

1) 逆轉(zhuǎn)數(shù)字的著名方法 ：從用戶輸入并將其類型轉(zhuǎn)換為整數(shù)，然后在循環(huán)中循環(huán)直到num在循環(huán)內(nèi)不為零：

• Find out the remainder.

  找出其余的。

• Using this: rev_num = rev_num * 10 + remainder.

  使用這個(gè)：rev_num = rev_num * 10 +余數(shù)。

• Update that number by diving by 10.

  通過(guò)跳水10來(lái)更新該數(shù)字。

• After coming out of the loop printing the reverse number.

  退出循環(huán)后，打印反向編號(hào)。

if __name__ == "__main__" :# take string input from usernum = int(input('Enter a number: '))rev_num = 0# iterate the loop till num is not equal to zerowhile(num) :rem = num % 10rev_num = rev_num* 10 + remnum //= 10print('Reverse number is: ', rev_num)

Output

輸出量

Enter a number: 12345 Reverse number is: 54321

2) Make a user-defined function for reversing the Number: Take input from the user and typecast into integer, thenreverseNum() function call.

2) 制作一個(gè)用于反轉(zhuǎn)Number的用戶定義函數(shù) ：從用戶那里輸入輸入并將其類型轉(zhuǎn)換為整數(shù)，然后調(diào)用verseNum()函數(shù)。

Inside the function:

函數(shù)內(nèi)部：

• Iterate in the loop till num does not become zero:

  在循環(huán)中迭代，直到num不為零：

• Find out the remainder.

  找出其余的。

• Using this: rev_num = rev_num * 10 + remainder.

  使用這個(gè)：rev_num = rev_num * 10 +余數(shù)。

• Update that number by diving by 10.

  通過(guò)跳水10來(lái)更新該數(shù)字。

• After coming out of the loop returning the reverse number to the main.

  退出循環(huán)后，將反向編號(hào)返回到主編號(hào)。

# define a function for finding # reverse of the number def reverseNum(num) :rev_num = 0# iterate the loop till num is not equal to zerowhile(num) :rem = num % 10rev_num = rev_num* 10 + remnum //= 10return rev_num# Main() method if __name__ == "__main__" :# take string input from usernum = int(input('Enter a number: '))print('Reverse number is: ', reverseNum(num))

Output

輸出量

Enter a number: 12345 Reverse number is: 54321
