Please bear with me, as I new to Python.

I have three dictionaries in three .txt files. Where the 'key' is the gene name followed by an integer for value. I would like to make a dictionary where I have a gene name followed by value1 from dict1, value2 from dict2, value3 from dict3.

So if key values are the same, build dictionary as key: (value2, value2, value3).

this is what I have so far where I define three txt files as dictionaries. 

with open(dictionaryfile1.txt, 'r') as dic1:
    dictionary1=eval(dic1.read())
with open(dictionaryfile2.txt, 'r') as dic2:
    dictionary2=eval(dic2.read())
with open(dictionaryfile3.txt, 'r') as dic3:
    dictionary3=eval(dic3.read())

Following are my dictionaries from .txt file.

dictionary1: 

 {'YAL008W': 25, 'YBR255W': 50, 'YGR164W': 37, 'YGR131W': 40, 'YNL003C': 11,

 'YIL059C': 25, 'YIL004C': 2, 'YNR018W': 33, 'YPL144W': 16}

Your help is much appreciated.

This is not a repeat as marked by two users because I have three dictionaries and It would be important for others to see how to link up three dictionaries instead of two. Thank you for your feedback

  • Suppose a gene is only in dicts 1 and 3, do you want a 3 item list (value1, None, value3) or a 2 item list (value1, value3)? – tdelaney Feb 23 '16 at 20:17
  • Although it is not the accepted answer, the first article in the duplicate message has a response that covers inconsistent keys. The one with 18+ votes is good. – rfportilla Feb 23 '16 at 20:20
  • @tdelaney Yes, value1, 0, value 3 if no value exists for that gene in dictionary 2. Because Id like to save this to an excel sheet later where I would have the gene name, followed by a value from dictionary 1, dictionary 2 value for that gene, and dictionary 3 value for that gene. – user5927494 Feb 23 '16 at 20:30
