Answer 1

if u mean like this
s = len(x)
while c < s:
u can do that

Answer 2

Thanks for your suggestion now i have solved the problem

Answer 3

You can use list comprehension and just append it to itself

x = ['ab','bc','cd','de']
x += [i.upper() for i in x]

print(x)

Basically the same as:

x = ['ab','bc','cd','de']
y = []
for i in x:
y.append(i.upper())
x += y

print(x)

Answer 6

Welcome Albert

Answer 7

that code probably would run forever
u append it to the original list, and that while loop's condition will never turn false
u can create another list to hold that new uppercast words

Answer 8

What if i will assign len to another variable before using while loop ?
