```Input : a = 806, b = 91
Output : 80691

Input : a = 5, b = 1091
Output : 51091

```

Method 1: One method of achieving this can be counting the number of digits of second number. Then multiply the first number with 10^digits and adding both the numbers. Below is the implementation.

 `# Python program to concatenate``# two numbers`` ` ` ` `def` `numConcat(num1, num2):`` ` `     ``# find number of digits in num2``     ``digits ``=` `len``(``str``(num2))`` ` `     ``# add zeroes to the end of num1``     ``num1 ``=` `num1 ``*` `(``10``*``*``digits)`` ` `     ``# add num2 to num1``     ``num1 ``+``=` `num2`` ` `     ``return` `num1`` ` ` ` `# Driver's code``a ``=` `906``b ``=` `91``print``(numConcat(a, b))`
Output:
```90691
```

Method 2: Another method can be converting both the numbers to the string. Then concatenate them and convert them back to integers. Below is the implementation.

 `# Python program to concatenate``# two numbers`` ` ` ` `def` `numConcat(num1, num2):``      ` `        ``# Convert both the numbers to``        ``# strings``        ``num1 ``=` `str``(num1)``        ``num2 ``=` `str``(num2)``         ` `        ``# Concatenate the strings``        ``num1 ``+``=` `num2``         ` `        ``return` `int``(num1)`` ` ` ` `# Driver's code``a ``=` `906``b ``=` `91``print``(numConcat(a, b))`

Output:

```90691
```
