Make a list

shoppi­nglist = ['bags', 'shoes', 'boots', 'shirts']
 
print (shopp­ing­lis­t[2])
 
item_n­umber = 0
 
"­"­"
while item_n­umber < len(sh­opp­ing­list):
print ("List item:",­sho­ppi­ngl­ist­[it­em_­num­ber])
item_n­umber = item_n­umber + 1
"­"­"
 
 
out = 0
for muids in shoppi­nglist:
out = out + 1
 
print(out)
 
Result =
boots
4

Reverse Code

word = input(­"­insert a word plz") Ex:phon

reverse =""
letter_num = 0

while letter_num < len(word):
reverse = word[l­ett­er_num] + reverse
letter_num = letter_num + 1

print ("Re­verse: "­,re­verse)

Result = nohp

Loop List

mylist = [1,2,3­,4,5,6]

mylist2 = ['a', 'b', 'c']

mylist3 = [1, 'b', 2.5]

print (mylist)
print (mylist2)
print (mylist3)

mynumbers = range(11)

for num in mynumbers:
print (num)

mylist­2.a­ppe­nd(­'an­other item')
print (mylist2)

Random: PYthon

import random


mylist = ['Red', 'Green', 'Blue', 'Yellow', 'Purple', 'Black']

print (mylist)

user_guess = input(­"­Guess a word: ")

random­_item = random.ch­oic­e(m­ylist)

print (rando­m_item)

if user_guess == random­_item:
print(­"­Correct Guess")
else:


if user_guess in mylist:
print ("Yes, in the list")
else:
print ("No, not in the list")
