For s in `sololearn`?

Question

s = `sololearn`
for i in s:
[print(i if("a" < i) else 0, end=")]
OUPUT: solole0rn
#How are they mixing letters as references?
#assuming "i" is every character in the string "sololearn", how am I to know what character is represented by "a"? If they said "replace l with zero, I would understand but how are they arriving at this? Thanks for any help.

Answer 1

When comparing strings the maximum is the one with the highest ASCII value.
All letters from b to z have higher ASCII values than the letter a. Therefore, the condition "a"<i holds true for them.
The only exception is "a"<"a", which is False. That's why a 0 is printed instead of the letter a.

Thanks Diego! I guess I havent gotten to the ASCII portion of Sololearn yet, so I'll google it now.
