keys(): ... print(student) ... Alice Bob Charlie Diana Ethan Fiona George Hannah In these examples, you first iterate over the keys of a dictionary using the dictionary directly in the loop header. In the second loop, you use the .keys() method to iterate over the keys. Both ...
if in above scenario, the correct way is to first store the modification somewhere else. Iterate the list entirely one time. Can use list.copy() or list[:] as the orignial list. Another example is looping through dictionary keys:

While iterating through a dictionary, you can access its keys and values at the same time. You can do this in two ways. The first method is to iterate through the dictionary and access the values using thedict[key]method. Then print each key-value pair within the loop: for key in my...
