I have to complete my assignment on inflation but I can’t understand that how deficit financing cause inflation? Help needed ! 

Can be possible if the Government increases taxes or cost on transport or electricity to cover up the deficit.

I'm not asking about how to cover up the deficit. I meant to say deficit financing is one of the causes of inflation?

Quit being a slacker and Google it up.

Thank you katzenminze, for your suggestion.

I’m not a slacker. I could not understand the cause that how deficit financing effect the inflation. But now I knew that and I can explain it, if you want to know.

Sure..

Yes indeed it can,

Deficit financing means the Governtment is spending more than it earns, and getting it financed from outside by borrowing  credit, inclusion of credit in the system means that the money supply has increased.
Increased money supply may infuse more demand and thus prices may go up to as consumers can pay more. But deficits are normally run to help employment and support businesses.
