Python Collection 20150209

Recently, the case using python is getting more and more gradually. But, I have used python not high frequently so I forget a lot of things and whenever I look for the way how to write basic python code. It is not reasonable. So I begin collecting the basic sample code.

Before I have written about python examples in following articles. Those articles are included this series.

If-else

if x > 0:
    print "X is bigger than 0."
else:
    print "X is less than 0."

If-elif-else

if x > 0:
    print "X is bigger than 0."
elif x == 0:
    print "X is zero."
else:
    print "X is less than 0."

File read and output(like cat which is major unix command line tool)

f = open('test-text.txt')
data = f.read()
f.close()
lines = data.split('\n')
for line in lines:
    if 0 < line.find(target) :
        print line

Send HTTP GET Requests

connection = httplib.HTTPSConnection(host)
connection.request("GET", uri)
response = json.loads(connection.getresponse().read())
print response

Send HTTP POST Requests

requestHeader = {"Content-type": "application/x-www-form-urlencoded"}
connection = httplib.HTTPSConnection(host)
connection.request("POST", uri, parameters, requestHeader)
response = json.loads(connection.getresponse().read())
print response

If post data is json format, Content-type should be below.

requestHeader = {"Content-type":"application/json"}
