FIFTH ASSIGNMENT

1)Get the key of a minimum value from the following dictionary.

Given Input:
sample_dict = {
  'Physics': 82,
  'Math': 65,
  'history': 75
}

Expected output: Math

SOL:

	d = {'Physics':82,'Maths':65,"history":75}
	m = float('inf')
	ans = ""
	for k,v in d.items():
 	   if(v<m):
    	    m = v
      	  ans = k
	print(ans)


2)Write a Python program to check if value 200 exists in the following dictionary.

Given Input:
sample_dict = {'a': 100, 'b': 200, 'c': 300}

Expected output:
200 present in a dict

SOL:

	s = {'a':100,'b':200,'c':300}
	found = False
	for k,v in s.items():
  	  if(v==200):
        found = True
	if found:
  	  print("200 present in a dict.")
	else:
  	  print("200 not present in a dict.")

3)Merge two Python dictionaries into one

Given Input:
dict1 = {'Ten': 10, 'Twenty': 20, 'Thirty': 30}
dict2 = {'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

Expected output:
{'Ten': 10, 'Twenty': 20, 'Thirty': 30, 'Fourty': 40, 'Fifty': 50}

SOL:

	 dict1 = {'Ten':10,'Twenty':20,'Thirty':30}
	 dict2 = {'Thirty':30,'Forty':40,'Fifty':50}
	 dict1.update(dict2)
	 print(dict1)
