Answer 1

date = input().replace(", ","/").replace(" ","/").split("/")

if date[0] in month:
date[0] = month[date[0]]
print("/".join([date[1],date[0],date[2]]))

Answer 2

Yes...have a look at regular expressions and use re.findall rather than using split(). on the date.. It might look daunting an the beginning (and I was dreading having to learn it) but they make task like this a lot easier

Answer 3

Same code, but much shorter with corrected use of dictionary lookup and other unnecessary loops eliminated. (I also shortened the dictionary keys for aesthetics):

#using len() and split() func
ia = input()
month= {"Jan":1, "Feb":2, "Mar":3, "Apr":4, "May":5, "Jun":6, "Jul":7, "Aug":8, "Sep":9, "Oct":10, "Nov":11, "Dec":12}

def conv_date_format(x):
x[0], x[1]= x[1], x[0]
return
if 8<=len(ia)<=10:
lista= ia.split("/")
else:
lista = ia.replace(",", "").split()
lista[0] = str(month[lista[0][:3]])
print("/".join(conv_date_format(lista)))
