在python中避免长时间使用L后缀

I have a dictionary which may have long values for some key. I want to convert this dictionary to string and send it to a server. But when I am converting it to a string using str(dict) function for the values which have a long value is suffixed with 'L'. This when I am sending it to a server the value it is generating a problem. So can anyone suggest me a easier way of what I can do to avoid the 'L' suffixI have a dictionary which may have long values
