# Python | Numpy np.ifft() method

With the help of `np.ifft()` method, we can get the 1-D Inverse Fourier Transform by using `np.ifft()` method.

Syntax : `np.ifft(Array)`
Return : Return a series of inverse fourier transformation.

Example #1 :
In this example we can see that by using `np.ifft()` method, we are able to get the series of inverse fourier transformation by using this method.

 `# import numpy ` `import` `numpy as np ` ` `  `a ``=` `np.array([``5``, ``4``, ``6``, ``3``, ``7``]) ` `# using np.ifft() method ` `gfg ``=` `np.fft.ifft(a) ` ` `  `print``(gfg) `

Output :

[ 5. + 0.j 0.2236068 – 0.21796276j -0.2236068 – 0.92330506j
-0.2236068 + 0.92330506j 0.2236068 + 0.21796276j]

Example #2 :

 `# import numpy ` `import` `numpy as np ` ` `  `a ``=` `np.array([``-``5.5``, ``4.4``, ``-``6.6``, ``3.3``, ``-``7.7``]) ` `# using np.ifft() method ` `gfg ``=` `np.fft.ifft(a) ` ` `  `print``(gfg) `

Output :

[-2.42 + 0.j -0.77 + 1.13774197j -0.77 + 3.30553221j -0.77 – 3.30553221j
-0.77 – 1.13774197j]
