Sometimes, while working with data, we can have a problem in which we require to gather a data that is of the form of sequence of increasing element tuple with each tuple containing the element N times. Let’s discuss certain ways in which this task can be performed. 

Method #1 : Using generator expression + tuple() The combination of above functions can be used to perform this task. In this, we need to iterate through N using generator expression and construction of tuple using tuple(). 

Python3




# Python3 code to demonstrate working of
# N element incremental tuples
# Using generator expression + tuple
 
# initialize N
N = 3
 
# printing N
print("Number of times to repeat : " + str(N))
 
# N element incremental tuples
# Using generator expression + tuple
res = tuple((ele, ) * N for ele in range(1, 6))
 
# printing result
print("Tuple sequence : " + str(res))

Output : 

Number of times to repeat : 3
Tuple sequence : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5))

Method #2 : Using repeat() + list comprehension This task can also be performed using combination of above functions. In this, we use repeat() to repeat elements N times. And iteration is handled using list comprehension. 

Python3




# Python3 code to demonstrate working of
# N element incremental tuples
# Using generator expression + tuple
from itertools import repeat
 
# initialize N
N = 3
 
# printing N
print("Number of times to repeat : " + str(N))
 
# N element incremental tuples
# Using generator expression + tuple
res = tuple(tuple(repeat(ele, N)) for ele in range(1, 6))
 
# printing result
print("Tuple sequence : " + str(res))

Output : 

Number of times to repeat : 3
Tuple sequence : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5))

Method #3 : Using for loop, while loop and tuple() method

Python3




# Python3 code to demonstrate working of
# N element incremental tuples
# Using generator expression + tuple
 
# initialize N
N = 3
 
# printing N
print("Number of times to repeat : " + str(N))
 
# N element incremental tuples
res=[]
for i in range(1,6):
    x=[]
    j=0
    while(j<N):
        x.append(i)
        j+=1
    res.append(tuple(x))
res=tuple(res)
# printing result
print("Tuple sequence : " + str(res))

Output

Number of times to repeat : 3
Tuple sequence : ((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5))
