# Python | Scipy integrate.dblquad() method

With the help of `scipy.integrate.dblquad()` method, we can get the double integration of a given function from limit a to b by using `scipy.integrate.dblquad()` method.

Syntax : `scipy.integrate.dblquad(func, a, b)`

Return : Return the double integrated value of a polynomial.

Example #1 :
In this example we can see that by using `scipy.integrate.dblquad()` method, we are able to get the double integration of a polynomial from limit a to b by using this method.

 `# import scipy.integrate.dblquad ` `from` `scipy ``import` `integrate ` ` `  `gfg ``=` `lambda` `y, x: x ``*` `y``*``*``2` ` `  `# using scipy.integrate.dblquad() method ` `geek ``=` `integrate.dblquad(gfg, ``0``, ``3``, ``lambda` `x: ``0``, ``lambda` `x: ``1``) ` ` `  `print``(geek) `

Output :

1.4999999999999998

Example #2 :

 `# import scipy.integrate.dblquad ` `from` `scipy ``import` `integrate ` `gfg ``=` `lambda` `y, x: x ``*` `y``*``*``2` `+` `2` `*` `x``*``y ``+` `4` ` `  `# using scipy.integrate.dblquad() method ` `geek ``=` `integrate.dblquad(gfg, ``1``, ``4``, ``lambda` `x: ``0``, ``lambda` `x: ``1``) ` ` `  `print``(geek) `

Output :

21.999999999999996
