import re
def ModifyString(s):
    w = re.split('(\d+)',s)
    numbers = []
    for word in w:
       if word.isdigit():
          numbers.append(int(word))
    numbers = sorted(numbers,reverse=True)
    k=0
    s=""
    for r in range(0,len(w)):
       if w[r].isdigit():
          w[r] = numbers[k]
          k=k+1;
       s = s+str(w[r]   )
    return(s)
    
s = "It is a 3days 4nights holiday trip"
w = ModifyString(s)
print("Original String: %s"%s)
