To set it up more,correct and fix error.
Capitale letters in method == 'POST'
Have remove GET to avoid to confusion.

foo\
app.py
    templates\
    index.htm

app.py

from flask import Flask,redirect,url_for,request,render_template

app = Flask (__name__)
@app.route('/')
def my_form():
    return render_template("index.html")

@app.route('/suc/<name>')
def suc(name):
    return "hello Boss %s" % name

@app.route('/login', methods=['POST'])
def log():
    if request.method == 'POST':
        user = request.form['nm']
        return redirect(url_for('suc', name=user))

if __name__ == '__main__' :
    app.run(debug=True)

index.html

<html>
   <body>
      <form action = "http://localhost:5000/login" method="post">
         <p>Enter Name:</p>
         <p><input type="text" name="nm" /></p>
         <p><input type="submit" value="submit" /></p>

Re: Python Import error

It's part of standar library,so it should work.
Here a run in Python 3.4.

>>> from http import cookies
>>> a_cooike = cookies.SimpleCookie()
>>> a_cooike['Base'] = 'cream'
>>> print(a_cooike)
Set-Cookie: Base=cream

The default placement for python 3.5 is terrible,what are developers thinking about?
C:\Users\hohait\AppData\Local\Programs\Python\Python35-32
I know the answer and it security relatet,but i don't like it.

Follow this,the you get better placement C:\Python35-32
Make sure under installation that you mark for Path and pip.
Test pip and upgrade pip.
Here a run and use virtualenv,so you see how pip work from clean setup.

C:\test\Scripts
λ activate

(test) C:\test\Scripts
λ python -m pip install --upgrade pip
Requirement already up-to-date: pip in c:\test\lib\site-packages

Re: With Python

I like python and I wanted to give it a try at web programming but the setup and management is too difficult. I'll just go back to php.

It's not so difficult,and you do not need stuff like LAMP.
Django and Flask has build in web-server this you use for all development local.

Try Flask is as easy as it get,try hello world example on the front page.
Run the 7 lines hello.py then it's a server,and you go to http://localhost:5000/ in browser to see result.

I use Flask for all my web-development,the simplicity and power it has to build all from small to bigger web apps is great.
Just a example of an simple image viewer,
i just iterate over some of my images and use CSS to organize little.
And i delpoy to web,you can see result here Image viewer

So it's like 40 lines of code and never used LAMP or any other stuff,just the build in web-server.
I talk more deploy and this stuff in this post.

server.py

from flask import Flask, render_template, jsonify
import os

app = Flask(__name__,static_url_path='')    
@app.route('/')
def img():
    pics = os.listdir('mysite/static/images')
    return render_template('img1.html', pics=pics)

if __name__ == '__main__':
  app.run()

index.html

 <!DOCTYPE html>
<html>
<head>
  <style>
    body {
      background: radial-gradient(#E0D9C6, #4B3A40);
    }
    h1 {
      text-align: center;
      font-weight: bold;
      color: #663333;
      font-size:60px;
    }
    .thumbnail {
      float: left;
      width: auto;
      margin: 2% 2% 30px 7%;
      height: 600px;
    }
  </style>
</head>
  <body>
     <h1>Image viewer</h1> …

Re: loop through list and exec one line at a time

Command you has to be string and you concatenate "line" inside os.system().
So if i have i list of words and want to now lenght of each word,
i can use linux command expr length.
The command get executed on each line of words.txt.

import os
import time

f = open('words.txt')
for line in f:
    line = line.strip()
    time.sleep(5)
    os.system('expr length ' + line)
f.close()

Re: How to split personal names in python using pandas

The problem can be solved before give data to Pandas.
As mention over there are lot of cases to think about.
I would have made up rules with regex.
Example.

 >>> import re

>>> s = "Richard Wayne Van Dyke"
>>> re.split(r"\s*(?:(?:[a-zA-Z]')|(Van \w.*))", s, re.I)[:-1]
['Richard Wayne', 'Van Dyke']
>>> s = 'Wayne Van Dyke'
>>> re.split(r"\s*(?:(?:[a-zA-Z]')|(Van \w.*))", s, re.I)[:-1]
['Wayne', 'Van Dyke']
>>> s = 'Edda Kathleen Van Heemstra Hepburn-Ruston'
>>> re.split(r"\s*(?:(?:[a-zA-Z]')|(Van \w.*))", s, re.I)[:-1]
['Edda Kathleen', 'Van Heemstra Hepburn-Ruston']

>>> s = "Gary Del Barco"
>>> re.split(r"\s*(?:(?:[a-zA-Z]')|(Del \w.*))", s, re.I)[:-1]
['Gary', 'Del Barco']

>>> s = 'Dave Allen Smith'
>>> re.split(r"\s*(?:(?:[a-zA-Z]')|(Del \w.*))", s, re.I)[:-1]
[]

So key word like Van and Del,in this regex will take key word and all word after as last name.
If need more rule than this,you have to make own make rule for problem names.
If pass in name that's not in regex,a empy list is returned.
