Calculate the ratio of male and female WeChat friends:

import itchat
 
itchat.login()
friends=itchat.get_friends(update=True)[0:]
male=female=other=0
for i in friends[1:]:
 sex=i['Sex']
 if sex==1:
  male+=1
 elif sex==2:
  female+=1
 else:
  other+=1
   
total=len(friends[1:])
malecol=round(float(male)/total*100,2)
femalecol=round(float(female)/total*100,2)
othercol =round(float(other)/total*100,2 )
 print ( ' Male friend: %.2f%% ' %(malecol)+ ' \n ' + ' Female friend: %.2f%% ' % (femalecol )+ ' \n ' + ' Friends of unknown gender: %.2f%% ' % (othercol))
 print ( "The display is as follows: " )
