1.
for i in range(100, 201):
y = []
for x in range(2, 12):
if i%x == 0:
y.append(1)
else:
y.append(0)
if sum(y)==0:
print("prime number ", i)

[dhansraj]

4th answer: Tried in a different way and works

newlist1=[]
for i in range(0, 30):
if not newlist1:
newlist1.append(i)
print('first', i)
elif len(newlist1)==1:
print(i+newlist1[0])
newlist1.append(i)
else:

Question on 3rd answer - no need to iterate over the list with a for-loop or did I miss something? Just get the smallest number, append to new, remove from existing and repeat using the while.

data_list = [25, 55, 78, 64, 25, 12, 22, 11, 1, 2, 44, 3, 122, 23, 34]
new_list = []

while data_list:
minimum = min(data_list)
new_list.append(minimum)
data_list.remove(minimum)

new_list.reverse(sort = True)
print(new_list)

Questions are okay. But most of the solutions can be further optimised..

For example palindrome can be check while interating string .just check I and n-1-i char ..mis match then false

I don't think reversed would take constant time..

[RoyalSuperCell]

l=[12, 43, 2, 35, 354, 5, 521]
for i in range(0, len(l)):
for j in range(i+1, len(l)):
if l[i]<l[j]:
l[i], l[j]=l[j], l[i]
print(l)


Without Using Sort Functiion

[gamespauls]

Just to suggest a fancy solution to Question 8 in 8:10

sentence = "Adeptus Mechanicus. Glory to the Machine God."

space_count = 0

for i in sentence:
if i.isspace() == True:
space_count += 1
word_count = space_count +1

print(word_count)

[sandeshvora]

3rd problem.. Variable name should be maximum.. Right?

[EveryThingOfficial]

Q1:
For num in range(100, 200) :
Cpt = 0
For i in range(2, num) :
If num % i != 0:
Cpt += 1
If cpt == num - 2:
Print(num)

Your're not wasting anyone's time -- we all come here to learn so don't skip anything, no matter how minute it is.

[GiorgosKimparis]

Very good work. I just to saying that Fibonacci first number is 0

[shantanuroy]

List in reverse :
for i in range(len(input_list)-1, -1, -1) :

print(reverse_list)

[pranjalsharma]

PALINDROME

s = input()
if s[0:] == s[::-1]:
print("palindrome")
else:
print("not palidrome")

[memeline]

q1 better solution
for i in range(101, 200):
if i %i==0:
print(i)

[romkainmotion]

some nice questions to play around with shortest or interesnig answer. For example for first question. There is much shorter solution with if statment, and it possible to do it with oneliner: print(*(i for i in range(100, 200) if i % 2 != 0), sep="\n") just for fun.

[nikunjrana]

Qus 1:
for x in range(100, 200, 2):
print(x)

[saikatghosh]

q.5>

li = [1, 2, 3, 4, 5, 6, 7, 8, 100]
l = li[::-1]
print(l)

this is also show same result ..is that right ?

[nishikanta]

Thanks a lot for video. I refreshed so many concepts

[enesuguroglu]

Here is alternative for question 3
def sort_list(x):
l = []
k = list(x)
for j in range(0, len(k)):
for i in k:
if i == max(k):
l.append(i)
k.remove(i)
print(l)

[naveenkumarg]

last question:
a='arrrbbb'
b=''
for i in a:
if i not in b:
b=b+i
b

[humanhelperorganization]

for Palindrome :
def palindrome(s):
return "Yes it is palindrome" if s[::-1].lower() ==s.lower() else "not a palindrome"
