I was going through the basic mathematical operation in python terminal and using format to manage the output.

I tried to generate output with the 10 decimal places.

print('{0:.10f}'.format(1.0/3))

Got this output 0.3333333333

Again I tried to generate output with the 20 decimal places

print('{0:.20f}'.format(1.0/3))

Got this output as 0.33333333333333331483

I think this should return 0.3333333333333333333

Why format function is not working as desired.

The format function is working normally. This is mainly because of the limitations of programming languages regarding floating point precision when producing decimals from division.

I encourage that you read about that here. https://docs.python.org/3/tutorial/floatingpoint.html
