Python pip  でモジュールインストールした時のError

# Python 始めました。


pythonなにかといいらしいので、勉強してみた機械学習AI Googleご愛用とか単価とか...

なのでClass を作成して学ぶ

### Pythonでclassを作ってみる。

```python:stu.py
'''
Study class 2017/9/3
create keisuke yamagishi
'''
class Study:

    def __init__(self, name, age):
        self.name = name
        self.age = age

    def callName(self):
        return self.name

    def callAge(self):
        return self.age

stu = Study("qiita", 24)

print stu.callName()
print stu.callAge()

```

##### 出力結果

```
->> python stu.py 
qiita
24
```
こんな感じで、出力されます。

コンストラクターに値を渡してその値がきちんと反映されているのが確認できます。


# PythonでHttp 通信してみる =====>> [::]

```python:study.py
import requests

class Study:

    def __init__(self,dns="https://google.com"):
        self.dns = dns

    def outputDns(self):
        print "Request: -> %s" % self.dns

    def requestGoogle(self):
        res = requests.get(self.dns)
        print (res)
        print (res.text)

s = Study()
# google Http request
s.outputDns()
s.requestGoogle()

```

*** ImportError: No module named request ****

上記エラーが出ましたので、pipにてインストール

```

むむむっ！

でましたぞ！！！

Permission denied:　左記エラーがてます！

なので、、、

sudoつけてみた、、、

```
sudo pip install requests

できました、これからPython始めます。
