The **`base64.urlsafe_b64encode()` method** encodes a byte-like object into binary form using the URL and file system safe alphabets. This encoding replaces `"+"` with `"-"` and `"_"` with `"/"` of the Base64 characters.


# Syntax
We can import `urlsafe_b64encode` from `base64` using the following code:
```python
from base64 import urlsafe_b64encode
```
The declaration of the `base64.urlsafe_b64encode()` method is as follows:
```python
base64.urlsafe_b64encode(b_string)
```

The method returns the encoded `bytes` for the byte-string provided as an argument.

# Code
The code below demonstrates the use of `base64.urlsafe_b64encode()`.

from base64 import urlsafe_b64encode
  
b_str = b'Python is awesome!'
print('Data type of \'b_str\': ', type(b_str))

enc_str = urlsafe_b64encode(b_str)
print('Data type of encoded \'enc_str\': ', type(enc_str))

print('Encoded string: ', enc_str)

## Explanation
In *line 3*, a byte string is initialized and stored in the variable, `b_str`. The next line prints the type of `b_str`. Then, in *line 6*, the string is encoded, and *line 7* prints the type of the encoded string. Finally, in *line 9*, the encoded string is printed.
