String not changing to uppercase

Question

I would like to know why am I not getting the desired output ? my code -

𝚖𝚢𝚕𝚒𝚜𝚝 = ['𝚏𝚛𝚎𝚎', '𝚌𝚘𝚍𝚎𝚌𝚊𝚖𝚙']
for i in 𝚖𝚢𝚕𝚒𝚜𝚝:
  print(i.upper())
print(𝚖𝚢𝚕𝚒𝚜𝚝)

OUTPUT -

𝚏𝚛𝚎𝚎
𝚌𝚘𝚍𝚎𝚌𝚊𝚖𝚙
['𝚏𝚛𝚎𝚎', '𝚌𝚘𝚍𝚎𝚌𝚊𝚖𝚙']

Desired OUTPUT -

FREE

['𝚏𝚛𝚎𝚎', '𝚌𝚘𝚍𝚎𝚌𝚊𝚖𝚙']

Answer 1

Your words are written in the mathematical monospace font for which there are no upper-case letters:

hex(ord(mylist[0][0]))
#'0x1d68f'
hex(ord('f'))
#'0x66' - this is the "normal f"
mylist[0][0] == 'f'
# False

So, technically everything works: i.upper() converts i to the upper case, but since there are no upper-case letters, the result of the conversion is the same string.
