[Solved] – Python – Convert list to tuple in Python

It ought to work fine. do not use tuple, list or different special names as a variable name. It’s most likely what is inflicting your drawback.

>>> l = [4,5,6]
>>> tuple(l)
(4, 5, 6)

Expanding on eumiro’s comment, usually tuple(l) can convert an inventory l into a tuple:

In [1]: l = [4,5,6]
In [2]: tuple
Out[2]: <type 'tuple'>
In [3]: tuple(l)
Out[3]: (4, 5, 6)

However, if you’ve redefined tuple to be a tuple rather than the type tuple:

In [4]: tuple = tuple(l)
In [5]: tuple
Out[5]: (4, 5, 6)

In [6]: tuple(l)
TypeError: 'tuple' object is not callable

In [6]: del tuple
In [7]: tuple
Out[7]: <type 'tuple'>

You might have done something like this:

>>> tuple = 45, 34 # You used `tuple` as a variable here
>>> tuple
(45, 34)
>>> l = [4, 5, 6]
>>> tuple(l) # Will try to invoke the variable `tuple` rather than tuple type.
Traceback (most recent call last):
    File "<pyshell#10>", line 1, in <module>
        tuple(l)
TypeError: 'tuple' object is not callable
>>>
>>> del tuple # You can delete the object tuple created earlier to make it work
>>> tuple(l)
(4, 5, 6)

Here’s the matter… Since you have got used a tuple variable to carry a tuple (45, 34) earlier… So, currently tuple is Associate in Nursing object of sort tuple currently…
It is no additional a sort and thus, it’s no additional due .
Never use any constitutional sorts as your variable name… you are doing have the other name to use. Use any impulsive name for your variable instead…

Example code,

#Convert list to tuple
listx = [5, 10, 7, 4, 15, 3]
print(listx)
#use the tuple() function built-in Python, passing as parameter the list
tuplex = tuple(listx)
print(tuplex)

Here is your sample code,

# Python code to convert into dictionary
def Convert(tup, di):
     for a, b in tup:
        di.setdefault(a, []).append(b)
     return di
# Driver Code
tups = [("akash", 10), ("gaurav", 12), ("anand", 14),
        ("suraj", 20), ("akhil", 25), ("ashish", 30)]
dictionary = {}
print (Convert(tups, dictionary))
