# Check for ascii values containing special characters

# return True

str2 = 'edpresso@educative.io'

print(str2, "has ASCII?:", str2.isascii())



# check for equivalent unicode to Asci

# return True

str3 = '/u0041' # Unicode of A

print(str3, "has ASCII?:", str3.isascii())



# Unicode value not having parallel ascii

# return False

str4 = 'ß'   # German letter
