1,180 PointsWhat's wrong with the odds function?
I tried the odds function separately in python Shell with slicing [::2], for e.g for "arunpatel", I got ['a', 'u', 'p', 't', 'l']. Is this not correct?
def first_4(str1):
str2 = list(str1)
if len(str2) >= 4:
list1 = str2[:4]
else:
return
return list1
def first_and_last_4(str1):
str2 = list(str1)
if len(str2) >= 8:
list1 = str2[:4] + str2[-4:]
else:
return
return list1
def odds(str1):
str2 = list(str1)
list1 = str2[::2]
return list1
