The below program is written to change the value of given dictionary such that the value word starts with upper case. However only the first value is changed with this program. Fix the program so that all values are changed.

key_values = {1:'michigan', 2:'detroit', 3:'southfield', 4: 'troy'}

def fix_key_value(key_values): for x in key_values: key_values[x] = key_values[x].title() return

fix_key_value(key_values) key_values
