Python - Loop Tuples

Loop Through Tuple Items

You can traverse the items in a tuple with Python's for loop construct. The traversal can be done, using tuple as an iterator or with the help of index.

Syntax

Python tuple gives an iterator object. To iterate a tuple, use the for statement as follows −

for obj in tuple:
   . . .
   . . .

Example

The following example shows a simple Python for loop construct −

tup1 = (25, 12, 10, -21, 10, 100)
for num in tup1:
   print (num, end = ' ')

It will produce the following output −

25 12 10 -21 10 100

Loop Through Tuple Items using Index

To iterate through the items in a tuple, obtain the range object of integers "0" to "len-1".

Example

tup1 = (25, 12, 10, -21, 10, 100)
indices = range(len(tup1))
for i in indices:
   print ("tup1[{}]: ".format(i), tup1[i])

It will produce the following output −

tup1[0]: 25
tup1 [1]: 12
tup1 [2]: 10
tup1 [3]: -21
tup1 [4]: 10
tup1 [5]: 100
