Unexpected Function Behavior In Python

I am working on cleaning up my code into defined functions for repeated tasks. The body of the code works fine when I run each block individually. However, when I define the function as follows, it just jumps to the else condition. How should I write the if and elif statements to the execute properly? Any recommendations how I can make this function more succinct? I'm still a beginner programmer. Thanks!

    if 'fb_used_items_raw':
        with open('fb_used_items_filtered.txt', 'w+') as file:
            for item in fb_used_items_raw:
                for k in wanted_keys_fb:
                    lines = item[k].split()
                    split_lines = [line for line in lines if line.strip()]            
                    file.write("{}".format(' '.join(split_lines)) + '\t')
            file.write('\n')
