Dictionary .get method usage in python


The method get() returns a value for the given key. If key is not available then returns default value None.


Following is the syntax for get() method −

dict.get(key, default=None)


  • key — This is the Key to be searched in the dictionary.
  • default — This is the Value to be returned in case key does not exist.

Return Value

This method return a value for the given key. If key is not available, then returns default value None.


The following example shows the usage of get() method.


diction = {'Name': 'Kumar', 'Age': 12}

print "Value : %s" %  diction.get('Age')
print "Value : %s" %  diction.get('School', "Nothing")

When we run above program, it produces following result −

Value : 12
Value : Nothing

Solution for : Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?

root@123:~# sudo apt-get install git
E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Remove your /var/lib/dpkg/lock file and force package reconfiguration.

sudo rm /var/lib/dpkg/lock
sudo dpkg --configure -a

It should work after this.
