This is a very simple question, you need to find the sum and average of all digits that appear in a string. For example,

```
# let declare a string
my_str = "This is 10th string in 23rd para"
```

Now, digits are **1 and 0 from 10** and **2 and 3 from 23**. So, the sum will be **1+0+2+3=6** and the average will be **6/4=1.5**.

Now, we will write a Python program to find the sum and average of numbers in a string.

## Code:

```
my_str = "This is 10th string in 23rd para"
digits=[]
for i in my_str:
if i.isdigit():
digits.append(int(i))
number_of_digits = len(digits)
total_sum = sum(digits)
average = total_sum/number_of_digits
print(total_sum)
print(average)
```
