Let's take the example , s = "Six-Year- Old". replace('-', '') , replace(' ', '') will going to replace all -'s and spaces with empty character respectively. lower() will lowercase all charecters.
So, cleaned will be, cleaned = 'sixyearold'.
Now, set(cleaned) stores all unique characters of cleaned. So, if count of all unique characters is same as length of cleaned then all characters of cleaned are unique.
len(set(cleaned)) == len(cleaned) will be True if all characters of cleaned are unique, else False.
Let's take the example ,
s = "Six-Year- Old"
.replace('-', '')
,replace(' ', '')
will going to replace all-
's and spaces with empty character respectively.lower()
will lowercase all charecters.So,
cleaned
will be,cleaned = 'sixyearold'
.Now,
set(cleaned)
stores all unique characters ofcleaned
. So, if count of all unique characters is same as length ofcleaned
then all characters ofcleaned
are unique.len(set(cleaned)) == len(cleaned)
will beTrue
if all characters ofcleaned
are unique, elseFalse
.Tnx Vidit Sarkar for your amazing explanation .
I appreciate that.
