So I am supposed to make a script that asks user to make a sentence then discard all characters but lower case and print the lower case letters like this ['m', 'y', 'p', 'a', 's', 's', 'w', 'o', 'r', 'd'].
My script:
#!/usr/bin/python3
sentence = input("Enter a sentence: ")
for letter in sentence:
if letter.islower():
print(letter)
and this is the output:
oeshisw r k
Seems like you want to produce a list, you have list comprehensions to make life easy:
l = ['P', 'm', 'y', 'H', 'p', 'a', 's', 's', 'w', 'o', 'r', 'd']
out = [i for i in l if i.islower()]
print(out)
# ['m', 'y', 'p', 'a', 's', 's', 'w', 'o', 'r', 'd']
Which is equivalent to:
out = []
for i in l:
if i.islower():
out.append(i)
print(out)
# ['m', 'y', 'p', 'a', 's', 's', 'w', 'o', 'r', 'd']
You might be looking for end = ","
:
sentence = input("Enter a sentence: ")
for letter in sentence:
if letter.islower():
print(letter, end=",")
# ^^^
Your program is almost OK, only instead of printing every lowercase character, append it to a list, and finally print only that list :
sentence = input("Enter a sentence: ")
lowercases = [] # prepare an empty list
for letter in sentence:
if letter.islower():
lowercases.append(letter)
print(lowercases) # print the filled list
Test:
Enter a sentence: The End of Universe.
['h', 'e', 'n', 'd', 'o', 'f', 'n', 'i', 'v', 'e', 'r', 's', 'e']
