Iterate over a dict except for x item items

Question

I have a dict in this format:

d_data = {'key_1':value_1,'key_2':value_2,'key_3':value_3,'key_x':value_x,'key_n':value_n}

and I have to iterate over it's items:

for key,value in columns.items():
    do something

except for the pair:

'key_x':value_x

Answer 1

Simply use the continue statement, to skip ahead to the next iteration of the for loop:

for key,value in columns.items():
    if key == 'key_x':
        continue
    # do something
