Write a function that gets a number between 1 and 20 from the user.Return the number. (Use a while loop to make sure you get a number inthat range) Write a function that sums the first n odd numbers (1 + 3 + 5 + ...). Use nas a parameter and return the sum. Write a mainline (code outside of a function) that: calls the first function to get a number n (between 1 and 20) calls the second function to get the sum of the first n odd numbers prints the sum143
Write a program whose input is two integers and whose output is the two integers swapped.
Ex: If the input is:
3 8
the output is:
8 3
Your program must define and call the following function. swap_values() returns the two values in swapped order.def swap_values(user_val1, user_val2)
I get all tests passed except one.: the one in the bold. It puts parentheses around the answer instead of what they want for output.
0 / 2
Output differs. See highlights below.

Write and test the “digit” function:
Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415 that is entered by user , then the call digit(n,0) would return the digit 2, and the call digit(n,2) would returnthe digit 4. do this only by using functions and loops. arrays are not allowed.
example :Input: n = 29415 , k = 1 output: 9
Input: n = 2 , k = 1 output: index out of bound (return -1)

- Write a program in Python for a (very) rudimentary shooter "game". You are the only shooter and you start with ammo of 10. The one enemy doesn't shoot back and starts with health of 5. Code a custom function named shoot that prints "Shot fired" and returns True for a hit or False for a miss. Generate a random 0 to assign False or 1 to assign True. In the main function, use a while loop that runs the shoot function until you run out of ammo, at which point you lose. Report both hits and misses (see Sample Outputs). If your shot is a hit as determined by the value returned by shoot, your code should lower the enemy's health. If you are lucky, the health of the enemy will be reduced to zero before you run out of ammo. If this happens, report the enemy's demise and use the break keyword to stop the loop. You have won.arrow_forwardWrite a program in python for a (very) rudimentary shooter "game". You are the only shooter and you start with ammo of 10.

- Write a function that does the following for the given values: add, subtract, divide and multiply. These are simply referred to as the basic arithmetic operations. The variables have to be defined, but in this challenge they will be defined for you. All you have to do is check the variables, do some string to integer conversions, use some if conditions, and apply the arithmetic operation. Examples operation ("1", "2", operation ("4", "5", operation ("6", "3", "add" ) → 3 "subtract") → -1 "divide") → 2arrow_forward1. Write a program uses a Boolean-valued function to determine whether a set of numbers is in a given range. a) Define a function, isInRange(x) with an integer parameter. b) isInRange(x) returns true if the integer number x is in the range (-100, 100). Otherwise, return false.c) Define a main() function, in which a loop will be created to do the following ten times: 1) get a random integer, n, in the range (-500, 500). 2) call isInRange(x) function to determine and print out if the number n is in the range. d) Call main() function to initiate the tasks to be performed. Output Example: 2 is in the range.66 is in the range.171 is not in the range. 67 is in the range.-28 is in the range.355 is not in the range. 343 is not in the range. 233 is not in the range. -263 is not in the range. 11 is in the range. 2.

Write a function named almost_equal that receives two floating point numbers and returns whether they are close enough to each other. Two floating points numbers are close enough to each other if they are within one-tenth of 1% (0.001). Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass. Hint: The fabs function in the math module of Python's libraries returns the absolute value of its parameter.arrow_forward
