Question

Python scrypting help!

The script must define 4 functions

read_file_into_integer_list

list_mean

list_median

list_range

read_file_into_integer_list

This functions must have the following header

This function must read in the numbers contained in a file, convert them to integers and add them to an array.
The function must return the array of integers it creates.

list_mean

This functions must have the following header

This function must calculate the average (mean) of the integers in a list.
It must return the the rounded average.

list_median

This functions must have the following header

This function must sort a list and return the value of the element in the middle of the list

list_range

This functions must have the following header

This function must return the difference between the highest and lowest number in a list.

Run code

At the bottom of the script you must have the following code

Testing

Your output should look like this

Explanation / Answer

# Python code begins

numbers = []
length=0

# Function definition is here
def read_file_into_integer_list(filename):
i=0
with open(filename) as f:
for line in f:
data = line.split()
for j in data:
numbers.append(int(j))
#print (numbers[i])
i=i+1;
length=i;

return numbers;

def list_mean(a2):
length=len(numbers)
mean =sum(a2)
return mean/length
  
  
def list_median(a3):
a3.sort();
length=len(a3)
middle=int(length/2)
return a3[middle]
  
  
def list_range(a4):
a4.sort();
length=len(a4)
#print(a4)
return a4[length-1]-a4[0]
  
  

# Now you can call printme function

numbers = read_file_into_integer_list("numbs.txt")
print("numbers: ", numbers)
print("list_mean(numbers): ", list_mean(numbers))
numbers.sort()
print("numbers: ", numbers)
print("list_median(numbers):", list_median(numbers))
print("list_range(numbers): ", list_range(numbers))

Sample Output :

numbers: [1, 2, 3, 4, 5, 6]
list_mean(numbers): 3.5
numbers: [1, 2, 3, 4, 5, 6]
list_median(numbers): 4
list_range(numbers): 5
