Given a variable `my_dict` which is a dictionary, consider you use it in a for loop in this manner:
```python
for x in my_dict:
print(x)
```
What are the contents printed out?
A. An error as we have not specified whether to iterate over keys or values
B. The keys in the dictionary
C. Tuples containing the key and value pairs
D. The values in the dictionary
Answer (2)
The output of the for loop will print the keys of the dictionary since by default, iterating over a dictionary in Python goes through its keys. Thus, the correct answer is option B. Each key will be printed in turn as the loop progresses.
;
When you use a dictionary in a for loop in Python like this:
for x in my_dict: print(x)
you are iterating over the keys in the dictionary. Therefore, the output will be the keys of the dictionary. ;
