Handle KeyError in Python

How can i handle KeyError with if's? Depending the error, handling the error from a diferrent way.

speed_uhc_team = counts_stats['games']['SPEED_UHC']['modes']['team_normal']
speed_uhc_solo = counts_stats['games']['SPEED_UHC']['modes']['solo_normal']

What i want is if the key team_normal don't exist in the dictionary assign a value of my choice to that key.

But when the key team_normal exists, just assign the key value.
