The question above has multiple choices as follows;
a. API
b. docstring
c. help
d. man
Well, I am stuck between B and C. I’ll however settle for (B) docstring.
Python docstrings provide an easier way to associate
documentation with python classes, modules and functions. The interactive help function
on the other is built in and is intended for interactive use. This function
exists to view help interactively. With the help feature, you can quickly learn
classes, modules, functions and many more.
They get the idea from nature and then the make engineered systems.That is how they are similar.
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")

Question:
Write one for loop to print out each element of the list several_things. Then, write another for loop to print out the TYPE of each element of the list several_things.
Answer:
The solution in python is as follows:
for element in several_things:
print(element)
for element in several_things:
print(type(element))
Explanation:
The solution assumes that the list several_things has already been initialized.
So, the rest of the code is explained as follows:
This line iterates through the list, several_things
for element in several_things:
This line prints each element
print(element)
This line iterates through the list, several_things for the second time
for element in several_things:
This line prints the type of each element
print(type(element))
D I,II and III is the answer i think
