Tip

• We should sort as per four groups
• myfilter() function is written to get four gourps.
• Sort each groups and concate them

 

Solution

s = input() def myfilter(s): lc = [] wc = [] on = [] en = [] for i in range(len(s)): c = s[i] if 'a' <= c and c <= 'z': lc.append(c) continue if 'A' <= c and c <= 'Z': wc.append(c) continue n = int(c) if 1 == (n%2): on.append(c) else: en.append(c) return lc, wc, on, en lc, wc, on, en = myfilter(s) lc.sort() wc.sort() on.sort() en.sort() s = '' s += ''.join(lc) s += ''.join(wc) s += ''.join(on) s += ''.join(en) print(s)
