## NumPy Mathematics: Exercise-32 with Solution

Write a NumPy program to calculate exp(x) - 1 for all elements in a given array

Sample Solution:-

Python Code:

``````import numpy as np
x = np.array([1., 2., 3., 4.], np.float32)
print("Original array: ")
print(x)
print("\nexp(x)-1 for all elements of the said array:")
r1 = np.expm1(x)
r2 = np.exp(x) - 1.
assert np.allclose(r1, r2)
print(r1)
```
```

Sample Output:

```Original array:
[1. 2. 3. 4.]

exp(x)-1 for all elements of the said array:
[ 1.7182817  6.389056  19.085537  53.59815  ]
```

## Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

```str="+++Welcome python+++"
str.strip()

print(str)```

Output:

`+++Welcome python+++`
