Python?
To iterate over a list or tuple in Python, you can use a for loop. Here's an example:
```
my_list = [1, 2, 3, 4, 5]
for item in my_list:
print(item)
```
This will print each item in the list on a new line.
If you have a dictionary, you can iterate over the keys, values, or both using the `items()` method. Here's an example:
```
my_dict = {'a': 1, 'b': 2, 'c': 3}
for key, value in my_dict.items():
print(key, value)
```
This will print each key-value pair in the dictionary on a new line.
If you have a string, you can iterate over each character using a for loop as well. Here's an example:
```
my_string = "Hello, world!"
for char in my_string:
print(char)
```
This will print each character in the string on a new line.
