## Python Math: Exercise-34 with Solution

Write a Python program to get the length and the angle of a complex number.

**Sample Solution**:-

**Python Code:**

```
import cmath
cn = complex(3,4)
#length of a complex number.
print("Length of a complex number: ", abs(cn))
# gets angle. return in radians, between [-π, π]
print("Complex number Angle: ",cmath.phase(0+1j) )
```

Sample Output:

Length of a complex number: 5.0 Complex number Angle: 1.5707963267948966
