Python Basic: Exercise-134 with Solution
Write a Python program to input two integers in a single line.
Sample Solution-1:
Python Code:
print["Input the value of x & y"]
x, y = map[int, input[].split[]]
print["The value of x & y are: ",x,y]
Sample Output:
Input the value of x & y 2 4 The value of x & y are: 2 4

Sample Solution-2:
Python Code:
a, b = [int[a] for a in input["Input the value of a & b: "].split[]]
print["The value of a & b are:",a,b]
Sample Output:
Input the value of a & b: 2 4 The value of a & b are: 2 4

Convert a dict to XML:
from xml.etree.ElementTree import Elementdef dict_to_xml[tag, d]:
'''
Turn a simple dict of key/value pairs into XML
'''
elem = Element[tag]
for key, val in d.items[]:
child = Element[key]
child.text = str[val]
elem.append[child]
return elem
When it is required to read two numbers and print the quotient and remainder when they are divided, the ‘//’ and ‘%’ operators can be used.
Below is a demonstration of the same −
Example
Live Demo
first_num = int[input["Enter the first number..."]] second_num = int[input["Enter the second number..."]] print["The first number is "] print[first_num] print["The second number is "] print[second_num] quotient_val = first_num//second_num remainder_val = first_num%second_num print["The quotient is :"] print[quotient_val] print["The remainder is :"] print[remainder_val]
Output
Enter the first number...44 Enter the second number...56 The first number is 44 The second number is 56 The quotient is : 0 The remainder is : 44
Explanation
The first and second numbers are taken as input from the user.
They are displayed on the console.
To find the quotient, the ‘//’ operator is used.
To find the remainder, the ‘%’ operator is used.
The operations output is assigned to two variables respectively.
This is displayed as output on the console.

I am new at this stuff as well. Did a bit of research from the python.org website and a bit of hacking to get this to work. The raw_input function is back again, changed from input. This is what I came up with:
i,j = raw_input["Enter two values: "].split[]
i = int[i]
j = int[j]
Granted, the code is not as elegant as the one-liners using C's scanf or C++'s cin. The Python code looks closer to Java [which employs an entirely different mechanism from C, C++ or Python] such that each variable needs to be dealt with separately.
In Python, the raw_input function gets characters off the console and concatenates them into a single str as its output. When just one variable is found on the left-hand-side of the assignment operator, the split function breaks this str into a list of str values .
In our case, one where we expect two variables, we can get values into them using a comma-separated list for their identifiers. str values then get assigned into the variables listed. If we want to do arithmetic with these values, we need to convert them into the numeric int [or float] data type using Python's built-in int or float function.
I know this posting is a reply to a very old posting and probably the knowledge has been out there as "common knowledge" for some time. However, I would have appreciated a posting such as this one rather than my having to spend a few hours of searching and hacking until I came up with what I felt was the most elegant solution that can be presented in a CS1 classroom.
