In this simple python program, we need to concatenate the numbers and calculate the sum. It is a beginner-level python program.
To understand this example, you should have knowledge of the following Python programming topics:
In this number python program example, we need to find the sum of concatenating of a number n using a pattern of n + nn + nnn. For example, let us take a number 5, and we have to use the pattern 5 + 55 + 555 = 615.
To solve the python problem, we first need to change the number 'n' to a string. Then we concatenate the string 'n' to 'nn' and 'nnn' then convert back the string to a number and calculate the sum of the concatenated numbers and print the result .
We use int
and str
functions of python language to convert the string to integer and then integer to string. Use a temp variable to store the string number, and then we concatenate the temp + temp to another variable. And temp + temp + temp to another variable. Finally, we calculate the sum by converting the string to an integer using int.
STEP 1: Enter the number using the input method and convert that input string to an integer using int()
in python programming.
STEP 2: Convert the integer to a string and store that value in a variable for concatenate.
STEP 3: Use two variables to store the values after concatenating the string using temp + temp and temp + temp + temp.
STEP 4: Now we have the strings, and convert the string to number using int()
and calculate the sum using python language.
STEP 5: Print the value of the result using a print statement in python basics.
n=int(input("Enter a number n: "))
temp=str(n)
t1=temp+temp # concatenate the strings
t2=temp+temp+temp
comp=n+int(t1)+int(t2) # calculate the sum
print("The sum is:",comp)
Enter the Number n : 5 The sum is : 615
