Now, we’re ready to program! Leave the visualizer and go to OnlineGDB to write your program. Here is the pseudocode for your program:
Define a function called “seven_checker” that will do the following things:
Iterate over a list.
Check to see whether the number 7 is in the list.
Print how many times the number 7 appears in the list.
Here is a possible implementation of the "seven_checker" function in Python:
```python
def seven_checker(lst):
count = lst.count(7)
print(f"The number 7 appears {count} time(s) in the list.")
```
This function takes a list as a parameter and uses the `count` method to count how many times the number 7 appears in the given list. Then, it prints the count using a formatted string.
You can call this function with your desired list to check the occurrences of the number 7, for example:
```python
my_list = [1, 2, 3, 4, 5, 6, 7, 7, 8, 9, 7]
seven_checker(my_list)
```
Output:
```
The number 7 appears 3 time(s) in the list.
```
