### Level 0

```sh

Compute 2**38 and hit at http://www.pythonchallenge.com/pc/def/274877906944.html

```

### Level 1

#####Two ways are there:

######1. Run this command in your terminal 

```sh

echo "g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj." | tr [a-xy-z] [c-za-b]

echo "map" | tr [a-xy-z] [c-za-b]

```

######2. Python script

```py

import string

tbl = string.maketrans(

    "abcdefghijklmnopqrstuvwxyz", "cdefghijklmnopqrstuvwxyzab"

)

st = "g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj."

print st.translate(tbl) # i hope you didnt translate it by hand. thats what computers are for. doing it in by hand is inefficient and that's why this text is so long. using string.maketrans() is recommended. now apply on the url.

url = "map"

url = url.translate(tbl)

```

### Level 2

```py

import urllib2,re,collections

r = urllib2.urlopen('http://www.pythonchallenge.com/pc/def/ocr.html').read()[843:]  # filter shit

print collections.Counter(r)    # shows that only alphabets are occurring once. So let's filter them out

code = re.findall("[a-zA-Z]", r)

code = "".join(code)

print code  # prints equality

```
