Write code to assign the number of characters in the string rv to a variable num_chars.

rv = "hello"

num_chars = len(rv)

print(num_chars)

Explanation:

*The code is in Python.

Initialize the string rv, in this example I set it to "hello"

Use the len() method to get the number of characters in the rv and set it to the num_chars

Print the num_chars

Note that the result will be 5 in this case, because hello consists of five characters

building and maintaining the topology is difficult and time consuming. the chance of redundant connections is high, which adds to the high costs and potential for reduced efficiency.
