Editing a python list

What I want to do?

I want to create a python program that takes a text file, makes the text into a list of strings like this
['Man', 'request', 'adapted', 'spirits', 'set', 'pressed.', 'Up', 'to'] (1)
, takes the number of letters of each word into a different list like this
[3, 7, 7, 7, 3, 8, 2, 2](2)
and checks that if the number of each string element is greater than 3 (>3), removes its first letter and adds it to the end of the word with 'xy' string too. The result of the final list should be:
['Man', 'equestrxy', 'daptedaxy', 'piritssxy', 'set', 'ressed.pxy', 'Up', 'to'](3)

What I have already done? I have made (1) and (2) parts of code and I am currently trying the (3) .

My code with comments:

text = open("RandomTextFile.txt").read().split()  #this is the the part (1) 



#function that creates the second part (2)

def map_(A): return list(map(len, A)) words = map_(text) #list that contains the example list of (2) 

#This is the part (3) and I try to achieve it by creating a loop
for i in range(y):
  if words[i]>3:
      text[i] = [x + string for x in text]

Can anyone suggest what I can do to achieve the part (3)? Thanks in advance!

For any word like this: t = 'request' you can use slicing:

t[1:]+t[0]+'xy'

Using list comphrehension

>>> x = ['Man', 'request', 'adapted', 'spirits', 'set', 'pressed.', 'Up', 'to']
>>> [i[1:] + i[0] + 'xy' if len(i) > 3 else i for i in x]

['Man', 'equestrxy', 'daptedaxy', 'piritssxy', 'set', 'ressed.pxy', 'Up', 'to']

You can do something like:

def format_strings(strs):
    len_strs = [len(s) for s in strs]
    return [strs[i][1:] + 'xy' if len_str > 3
        else strs[i] for i, len_str in enumerate(len_strs)]
