Complete the bodies of the if-else statements in the for loop: if the key is in the dictionary langs_count, add 1 to its current value, else add the key to langs_count and set its value to 1. Use the loop variable entry in your code.
# If the language is in langs_count, add 1
if entry in langs_count.keys():
langs_count[entry] += 1
# Else add the language to langs_count, set the value to 1
else:
langs_count[entry] = 1
