This is for Python
numbers = [7, 3, 6, 9, 0]
print(numbers.sort())
Output: [0, 3, 6, 7, 9]
numbers = [7, 3, 6, 9, 0]
print(numbers.sort(reverse = True))
Output: [9, 7, 6, 3, 0]

Answer:
def select_short_strings(string_list):
new_list = []
for s in string_list:
if len(s) < 20:
new_list.append(s)
return new_list
lst = ["apple", "I am learning Python and it is fun!", "I love programming, it is easy", "orange"]
print(select_short_strings(lst))
Explanation:
- Create a function called <em>select_short_strings</em> that takes one argument <em>string_list</em>
Inside the function:
- Initialize an empty list to hold the strings that are less than 20
- Inside the loop, check the strings inside <em>string_list</em> has a length that is smaller than 20. If found one, put it to the <em>new_list</em>.
- When the loop is done, return the <em>new_list</em>
- Create a list to check and call the function
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")
