# Python Math: Create an ASCII waveform

## Python Math: Exercise-66 with Solution

Write a Python program to create an ASCII waveform.

Sample Solution:-

Python Code:

``````from time import sleep
from math import sin, cos, radians

# increase 40 to get more wave
for n in range(1, 40):
circle_1 = 50 * (1 + sin(radians(n*10)))
circle_2 = 50 * (1 + cos(radians(n*10)))
print("#".center(int(circle_1)))
print("*".center(int(circle_2)))
sleep(0.05)
```
```

Sample Output:

## 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+++`
