Question

Can anyone explain this code line by line, what it is, what is it doing?

lst = []
print("Enter 10 numbers: ") #flag indication if a specfic condition exist
flag = False #
for x in range(10):
num = eval(input())
if(num >= 100):
flag = True
lst.append(num)
if(flag):
print("Warning: value over 100 has been entered.")
maxVal = lst[0]
minVal = lst[0]
total = 0
avg = 0
for y in lst:
if(maxVal < y):
maxVal = y
if(minVal > y):
minVal = y
total += y

print("Maximum =",maxVal)
print("Miniimum =",minVal)
print("Average =",(total/10))

Hello, I have explained every statement using comments. Please check and let me know if you have any doubts. Thanks.

I have also attached screen shot of the code also. If any compilation error related to Code indentation occurs please compare and correct the code with screen shot.

CODE

"""
In this program user inputs 10 numbers
and prints maximum, minimum and average value of
input numbers
"""

#creating a list named lst
#list is a collection which is ordered and changeable.
lst = []

#printing prompt for 10 numbers
#print() function prints the specified message to the screen
print("Enter 10 numbers: ")

#set flag as false
#flag indication if a specfic condition exist
flag = False

#inputs numbers using for loop with range
#start from index 0 to index 9
for x in range(10):
  
   #inputs number
   #eval is used to evaluate input
   num = eval(input())
  
   #if any number is greater than zero
   if(num >= 100):
       #set flag as true
       flag = True

   #appending number to list lst
   lst.append(num)

#if flag is true
if(flag):
   #print warning message
   print("Warning: value over 100 has been entered.")

#set maximum value as value in index 0 of lst  
maxVal = lst[0]

#set minimum value as value in index 0 of lst  
minVal = lst[0]

"""
We can't set maximum and minimum value as zero
if all values in the list are negative
it will make logical error
"""

#set total as zero
total = 0

#set average as zero
avg = 0

#iterates each element in list
for y in lst:
   #if current index value is greater than maxVal
   if(maxVal < y):
       #set maxVal as current index value
       maxVal = y
      
   #if current index value is less than minVal
   if(minVal > y):
       #set minVal as current index value
       minVal = y
  
   #adding current index value to total
   total += y

#printing maximum value
print("Maximum =",maxVal)

#printing minimum value
print("Miniimum =",minVal)

#printing average of 10 numbers
print("Average =",(total/10))
