I'm new to python and trying to figure out how to iterate through a nested tuple.
here is a tuple:
x=((1,2,('a', 'b', (6,9,7)), 6,('$','@')))
I'm trying to iterate so I can print each value separately like:
1
2
a
b
6
9
7
6
$
@
Here is my code, please let me know what I'm doing wrong here:
x=((1,2,('a', 'b', (6,9,7)), 6,('$','@')))
f=0
for y in x:
print(x[f])
f = f+1
You can try with recursion. Check if element is tuple, if it is then make a recursive call to function, if it is not then print it.
x=(((1,2,3,4),2,('a', 'b', (6,9,7)), 6,('$','@')))
def foo(a):
for b in a:
if isinstance(b,tuple):
foo(b)
else:
print b
foo(x)
Output:
1
2
3
4
2
a
b
6
9
7
6

A slight modification of Mohammad Yusuf's answer with a few QOL changes:
def foo(a, depth=0, depth_lim=10, indent_size=1, indent_str="-"):
# Set up indent and increment depth counter
indent = indent_str * ((depth) * indent_size)
depth += 1
#Loop over elements and print if we're not at the depth limit
if depth <= depth_lim:
for b in a:
if isinstance(b, tuple):
foo(b, depth, depth_lim, indent_size, indent_str)
else:
print(indent + str(b))
else:
print("Depth limit reached (" + str(depth_lim) +
"). Increase depth_lim for deeper printing.")
Example use:
test_tuple = ("a",(("c"),("d"),(("e"),("f"))), "b")
foo(test_tuple, indent_size=2)
Output:
a
--c
--d
----e
----f
b
