Status Report sending using python
First of all, Welcome to CodeReview!

Let's analyse the code to see what could be improved here.


current_Time = strftime("%H")
print current_Time
# convert str to number
cTime = int(current_Time)



A few things could be improved here:


Too many calls! current_Time = int(strftime("%H")) would have sufficed
the comment # convert str to number adds no real value to the code readability



s = smtplib.SMTP('smtp.gmail.com', 587)




Use better names, s does not make it clear what it does.
Avoid "magic" numbers-- it would have been better to have these as named constants



f = open('Readme.md', 'r')




Use context managers (with open ... as ...), see the docs




Some random thoughts


Use guards-- that way your script can be imported by other modules. Might not need it here, but I think it is good practice to always use them.
Consider upgrading your python-2.7 to python-3 and port all your code, since the Python 2 End Of Life is just 2 years away!
