How do you select lower and uppercase characters in a string using an if-else statement in Python?

I'm trying to solve a problem where I wish to select multiple words beginning with 's', but have both the lowercase and uppercase words be shown in the output.

To try and achieve my desired result, I used an if-else statement in a for-loop but it only selected the first value I chose. For example, if I wrote 'S' first, it selected the uppercase and ignored the lowercase.

st = 'Sally sells shakes from Shake Shack every Saturday.'

for i in st.split():
 if i[0] == 's' and 'S':
        print(i)

I expected the output to be: sells shakes Sally Shake Shack Saturday

But the actual output was: sells shakes

use logical OR: Return True if one of the statements are True : Your word will start with 'S' or 's'

NOTE: i[0] == 's' and 'S', is not correct expression in this case

STATEMENT1: i[0] == 's'

STATEMENT2: i[0] == 'S'

if STATEMENT1 or STATEMENT2

st = 'Sally sells shakes from Shake Shack every Saturday.'

for i in st.split():
   if i[0] == 's' or i[0] == 'S':
       print(i)

You can use lower() to make comparison lowercase:

st = 'Sally sells shakes from Shake Shack every Saturday.'

for i in st.split():
    if i.lower().startswith('s'):
        print(i)

result:

Sally
sells
shakes
Shake
Shack
Saturday.
