- Fetching the Files
- Reading the Data
We can download data from a serer using python's module which handle ftp or File Transfer Protocol. We can also read the data and later save it to the local system.
We need to install the module ftplib to acheive this.
pip install ftplib
Fetching the Files
We can fetch a specific file by using the get file method. This method moves a copy of the file from the remote system to
the local system from where the ftp connection was initiated.
import ftplib
import sys
def getFile(ftp, filename):
try:
ftp.retrbinary("RETR " + filename ,open(filename, 'wb').write)
except:
print "Error"
ftp = ftplib.FTP("ftp.nluug.nl")
ftp.login("anonymous", "ftplib-example-1")
ftp.cwd('/pub/') change directory to /pub/
getFile(ftp,'README.nluug')
ftp.quit()
When we run the above program, we find the file README.nlug to be present in the local system from where the connection was initiated.
Reading the Data
In the below example we use the module urllib2 to read the required portion of the data which we can copy and save it to local system.
When we run the above program, we get the following output −
import urllib2
response = urllib2.urlopen('http://www.tutorialspoint.com/python')
html = response.read(200)
print html
When we run the above program, we get the following output −
pip install ftplib
