TUPLE

Welcome to TUPLE

How will you find out count of tuples occurrence in list of tuples? which option will you give correct result?Input = [[('a', 'c')],[('a', 'b')], [('a', 'b')]]

for x in Input: Output[x[0]] += 1 print(Output)

Using counter and chain: Output = Counter(chain(*Input))

Output = Counter((*Input))

How will you sort a list of tuples by first Item?Input : [('45', 10), ('25', 5)]
Output : [('25', 5), ('45', 10)]

Using the Bubble Sort way,def Sort(tupll): lst = len(tupl) for i in range(0, lst): for j in range(0, lst-i-1): if (tupl[j][0] > tupl[j + 1][0]): temp = tupl[j] tupl[j]= tupl[j + 1] tupl[j + 1]= temp return tupl

def Sort_Tuple(tup): tup.sort(key = lambda x: x[0]) return tup print(Sort_Tuple(tup))

def Sort_Tuple(tup): tup.sort(key = lambda x: x[2]) return tup print(Sort_Tuple(tup))

Using the Bubble Sort way,def Sort(tupll): lst = len(tupl) for i in range(0, lst): for j in range(0, lst-i-1): if (tupl[j][0] < tupl[j + 1][0]): temp = tupl[j] tupl[j]= tupl[j + 1] tupl[j + 1]= temp return tupl

How to sort a list of tuples alphabetically?Input: [("aaaa", 2), ("aa", 3), ("bab", 9)]
Output: [('aa', 3), ('aaaa', 2), ('bab', 9)]

Using Bubble sort : def SortTuple(tup): n = len(tup) for i in range(n): for j in range(n-i-1): if tup[j][0] > tup[j + 1][0]: tup[j], tup[j + 1] = tup[j + 1], tup[j] return tup

Using sort() method: def SortTuple(tup): tup.sort(key = lambda x: x[0]) return tup print(SortTuple(tup))

Using sorted() method: def Sort_Tuple(tup): return(sorted(tup, key = lambda x: x[0])) print(Sort_Tuple(tup))

def Sort_Tuple(tup): return(sorted(tup, key = lambda x: x[1])) print(Sort_Tuple(tup))

Find out count of tuples occurrence in list of tuplesimport collections
Output = collections.defaultdict(int)
Input = [[('a', 'c')],[('a', 'b')], [('a', 'b')]]
for elem in Input:
Output[elem[0]] += 1
print(Output)

True

false

John has bought 5 products. we have a list which contains product name and its price. Create one tuple which is sorted based on price.lst = [('Key', 101), ('Lock', 320), ('Hammer', 100), ('Spanner', 67), ('wire', 93)]

import operator
print(sorted(lst, reverse = True, key = operator.itemgetter(1)))

will it give the correct result?

yes

no

Write a program to remove empty tuple from a list of tuples.lst1= [(), ('vikas', 5), ('mohan', 11), (), ('Harsha', 115),()]

lst2 = []

for item in lst1:

if len(item) != 0:

lst2.append(item)

print(lst2)

Yes

Write a program to create following 2 lists: - a list of names - a list of roll numbersGenerate and print a list of tuples containing name, roll number from the 2 lists. From this list generate 2 tuples—one containing all names, another containing all roll numbers.
