Convert nested tuple to custom key dictionary

sample_tuple = ((4, 'Gfg', 10), (3, 'is', 8), (6, 'Best', 10))

print("The original tuple : " + str(sample_tuple))

res = [{'key': sub[0], 'value': sub[1], 'id': sub[2]} for sub in sample_tuple]

print("The converted dictionary : " + str(res))


program to sort a list of tuples by second Item

def Sort_Tuple(tup):

lst = len(tup)

for i in range(0, lst):

for j in range(0, lst-i-1):

if (tup[j][1] > tup[j + 1][1]):

temp = tup[j]

tup[j]= tup[j + 1]

tup[j + 1]= temp

return tup

tup =[('for', 24), ('for', 10), ('programming', 28),

('python', 5), ('solution', 20), ('engineers', 15)]

print(Sort_Tuple(tup))


Tuples Manipulation

try:
      l=['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
      print 'List :',l
      tup1 = tuple(l) #Converts a list into tuple
      tup2=(1,2,3,4,5,6,7)
      #Adding two Tuples
      tup=tup1+tup2
      print 'New added tuple :',tup
      ntup=tup2*2
      print 'New multiplyed tuple:',ntup
      p=max(tup1)
      print 'The tuple with max value:',p
      p1=min(tup1)
      print 'The tuple with min value:',p1
      #Compares elements of both tuples and same return 0 otherwise -1
      k=cmp(tup2,ntup)
      print k
      #Delete Tuple
      del tup
      print tup
except:
      print 'Tuple does not exist'

Creation and accessing values in Tuples

t=(22,33,44,55,66,77,88,99) #A tuple is a sequence of immutable Python
print 'Tuple elements : ',t
#Accessing Values in Tuples
print 'Tuple first element :',t[0]
print 'tuple last element :',t[len(t)-1]
print '\n'
for i in t:
      print 'Elements in tuple: ',i
print '\n'
for i in range(len(t)):
      print 'Index :',i,'Vaule:',t[i]
