shift numbers -2

given a string, write a program to move all the numbers in it to its start.

input

the input will contain a string A.

output

the output should contain a string after moving all the numbers in it to its start.

explanation

for example, if the given string A is "1good23morning456",the output should be "123456goodmorning",as it contains numbers at the start.

sample input 1

1good23morning456

sample output 2

123456goodmorning

sample input 2

com876binat25ion

sample output 2

87625combination

sum prime numbers in the input

given a list of integers, write a program to print the sum of all prime numbers in the list of integers.

note.one is either prime nor composite number.

input

the input will be a single line containing space separated integers..

output

the output should be a single line containing the sum of all prime numbers from 1 to N

explanation

for example, if the given list of integers are

2 4 5 6 7 3 8

as 2,3,5 and 7 are prime numbers,your code should print the sum of these numbers. so the output should be 17

sample input 1

2 4 5 6 7 3 8

sample output 1

17

sample input 2

65 87 96 31 32 86 57 69 20 42

sample output 2

31

given a four digit number N as input. write a program to print first and last digit of the number

Find latitude and longitude of utmost 20 countries, ordered by population, with a population greater or equal to the population limit given below and have atleast one currency exclusively for themselves. (countries like Madagascar, Sri Lanka but not India, USA). Use the country details from this dataset.

Your task is to find the sum of the length of all lines (in kms) that can be drawn between co-ordinates of these countries.

Assume radius of earth: 6371 km

Round length of each line and final result to 2 decimal points

If co-ordinates are missing for any country use 0.000 N 0.000 E

Population limit: 84497

Note: Population limit will change at random intervals. So please make sure answer is computed for the correct population limit before submitting.

1. Develop a flowchart to calculate the tuition fee for a student at an University. The program should prompt for and accept the idnumber and the total number of credits for which he/she has enrolled. The bill outputted should contain the idnumber and tuition fee.

Calculate the tuition fee as follows:

• Total credits of 15 or more indicates that the student is full-time. Full-time students pay a flat rate of $35,000 for tuition. 
• Total credits of less than 15 indicate that the student is part-time. Part-time students pay $850 per credit for tuition.   

After printing the tuition fee, ask the user if s/he wants to calculate the tuition fee for another student – “Y” for yes and “N” for no. (This question is asked each time the tuition fee is printed). If s/he does, allow him/her to enter another student’s idnumber and total number of credits and find the tuition fee again. If the answer is no, the flowchart must be terminated with an appropriate message.

Riya took part in a maths quiz competition. To win the prize money she has to solve a tricky question at the end.For a given list of integers, write a program where all the integers in a given index range to be added.
She will be given M multiple ranges, where she should print the sum of numbers for each corresponding range.

Note: The limits in the range are both inclusive.

Input
The first line f input is space-separated integers.
The second line of input is a positive integer M denoting the number of index ranges.
The next M lines contain two space-separated integers of the range.

Output
The output should be M lines.
Each line contains an integer that represents the sum for the corresponding ranges.

Sample Input1
1 3 4 5 6
5
3 5
Sample Output1
12

Create a program that will allow the user to easily manage a list of names.

You should display a menu that will allow them to add a name to the list, change a

name in the list, delete a name from the list or view all the names in the list.

There should also be a menu option to allow the user to end the program. If they

select an option that is not relevant, then it should display a suitable message.

After they made a selection to either add a name, change a name, delete a name or

view all the names, they should see the menu again without having to restart the

program. The program should be made as easy to use as possible.

 Your younger brother is studying in school. His computer teacher gives homework to make a calculator for six operations: addition, subtraction, multiplication, division, power, and modulo on two integers. As you are about to become an engineer, so he expected help from your side to develop the program. Therefore, write Calc.py module that define a separate function for implementing all the above-mentioned operations. Then import Calc.py in your RollNo_W12A_1.py file. In RollNo_W12A_1.py, define a function Arithmatic(a, b, op) which calls the respected function defined in Calc.py to perform the required operation. Also handle the possible exceptions and display the

Sanjay identifies that for compiler designing he need to implement tokenization of a specific line of program. As a friend of Sanjay, your task is to help him to write a python function Tokenize_Line(fname, n) which reads n^th line from prime.py file and returns a list containing all tokens of that line as shown in the example. Also, handle the possible exception and provide proper message.

Contents of prime.py file will be like:

from math import sqrt

n = 1

prime_flag = 0

if(n > 1):

   for i in range(2, int(sqrt(n)) + 1):

       if (n % i == 0):

prime_flag = 1

           break

   if (prime_flag == 0):

       print("true")

   else:

       print("false")

else:

   print("false")

Input:

prime.py
