Tom is correct, but no one voted him up however for the satisfaction who voted up ghostdog74 I will mix and write this code, works for me, should work for you guys.

import ftplib
server="localhost"
user="user"
uploadToDir="public_html"
password="test@email.com"
try:
    ftp = ftplib.FTP(server)    
    ftp.login(user,password)
except Exception,e:
    print e
else:    
    filelist = [] #to store all files
    ftp.retrlines('NLST',filelist.append)    # append to list  
    num=0
    for f in filelist:
        if f.split()[-1] == uploadToDir:
            #do something
            num=1
    if num==0:
        print "No public_html"
        #do your processing here

first of all if you follow ghost dog method, even if you say directory "public" in f, even when it doesnt exist it will evaluate to true because the word public exist in "public_html" so thats where Tom if condition can be used so I changed it to if f.split()[-1] == uploadToDir:.

Also if you enter a directory name somethig that doesnt exist but some files and folder exist the second by ghostdog74 will never execute because its never 0 as overridden by f in for loop so I used num variable instead of f and voila the goodness follows...

Vinay and Jonathon are right about what they commented.
