Mr. President (Problem 43) - InfyTQ Solution in Python

Mr. President (Problem 43)

InfyTQ Solution in Python

PROBLEM STATEMENT

CSE160-Midterm-2015 Spring

You have a list of dictionaries with the following general structure:
presidents =
[ {'name':'George Washington', 'vp':'John Adams'},
{'name':'John Adams', 'vp':'Thomas Jefferson'},
{'name':'Zachary Taylor', 'vp':'Millard Fillmore'},
{'name':'Dwight D. Eisenhower', 'vp':'Richard Nixon'},
{'name':'Richard Nixon', 'vp':'Spiro Agnew'},
{'name':'Richard Nixon', 'vp':'Gerald Ford'}, ....]

For example, George Washington was a president who had John Adams serve as his Vice President ("vp").
Note that if a president served for more than one term or had multiple vice presidents, there could be multiple dictionaries listed for that president.

promoted_vp_ (presidents) will return the list of all vice presidents that also served as president.
E.g. if presidents consists of only the dictionaries listed above:
It returns the list {'John Adams', 'Richard Nixon'}

SOLUTION

#PF-Prac-43 def find_promoted_vp(presidents_dict): #start writing your code here lst=[] for i in presidents_dict: lst.append(i['vp']) promoted_vp_list=[] for i in presidents_dict: if i['name'] in lst: if i['name'] not in promoted_vp_list: promoted_vp_list.append(i['name']) return promoted_vp_list def find_presidents_vp(presidents_dict,duration): #start writing your code here lst=[] promoted_vp_list=[] for i in presidents_dict: lst.append(i['vp']) for i in presidents_dict: if(i['name'] in lst and i['period']==duration): if i['name'] not in promoted_vp_list: promoted_vp_list.append(i['name']) return promoted_vp_list presidents_dict=[{'name':'George Washington', 'vp':'John Adams','period':'1990-1993'}, {'name':'John Adams', 'vp':'Thomas Jefferson','period':'1994-1996'}, {'name':'Zachary Taylor', 'vp':'Millard Fillmore','period':'1997-1999'}, {'name':'Dwight D. Eisenhower', 'vp':'Richard Nixon','period':'1999-2001'}, {'name':'Richard Nixon', 'vp':'Spiro Agnew','period':'2001-2002'}, {'name':'Richard Nixon', 'vp':'Gerald Ford','period':'2002-2004'}] print("The president and vice president details:",presidents_dict) output=find_promoted_vp(presidents_dict) print("The list of vice presidents who also got promoted as presidents:",output) duration='1999-2005' print("The president and vice president details:",presidents_dict) print("Given duration:",duration) output1=find_presidents_vp(presidents_dict, duration) print("The list of vice presidents who also got promoted as presidents in the given duration:",output1)
