We can loop through the keys (disregarding the values) in a dictionary using the dict.keys() method.

Given the below dictionary named scores:


        
        
            
                
                
                    scores = {'Andrew':77, 'Matt': 80, 'Bob':90}

To loop through its keys:


        
        
            
                
                
                    for student in scores.keys():
   print(student)
                
            
            Andrew
Matt
Bob

student here is an arbitrary temporary variable name, so any other variable name would also work perfectly fine.
