Question

You receive an encrypted text(attached) which was encrypted using a substitution cipher. Can you find the key?

Tip: Google Letter frequency and remember (reuse) what you have implemented for the assignment. For instance, there is only a certain amount of 1, 2 or 3 wetter words where some are very common.

Note, the text does not contain upper cases letters.

Note2, special characters, numbers, etc are simply ignored.

Note3, use your previous findings and not findings you find online!

rev_key = {'a':'', 'b':'', 'c':''} #incomplete key; fill it with your findings

def decipher(a_string):

"""here goes code to decipher the text"""

  

global rev_key

  

decrypt = ""

  

return decrypt

def

get_text1_freq_dict():

  

d = {}

  

#returns a dictionary containing the frequencies in the format

#X.XXX (e.g., 0.011 or 0.129) for the letters. A sample entry

  

# would be freq = {'a':0.011}

  

return d

def get_text2_freq_dict():

  

d = {}

  

#returns a dictionary containing the frequencies in the format

  

#X.XXX (e.g., 0.011 or 0.129) for the letters. A sample entry

  

# would be freq = {'a':0.011}

  

return d
