It is a very critical error and comes most of the time while doing the programming of Python. Why does the str not tuple in Python occur in the very first place, and how you can get rid of it.

When you use a tuple instead of just using str, it will give an error.

Oops! This is a common mistake that can be easily fixed. Just use ‘tuple’ instead of str for the output tone of voice in Python.

We can use the try: and an except: function to fix the str, not tuple error but it is not a good programming practice to do so. So, we have come up with some pretty straightforward methods to kick off this error in a proper way.

How to fix ‘TypeError: Must be str, not tuple’ in Python

You should avoid getting these errors because TypeErrors can make your application load. Even after fixing it with the above-mentioned functions because the code is still up and consuming resources in the background.

TypeError: Must be str, not tuple in Python happening whenever you are not mentioning the tag or the function that is:

str()

Or sometimes, you need to mention the values of its also like in the example:

str(function(argument))

In the above example, you must pass out the name of the function, and if there you did call argument also so, don’t forget to call that one too.

Why does it always happen on the list?

The list is a function of Python which is using most of and most of the time it shows the error that list has not to attribute str so, in this case, you need to solve the error like in this example:

list()

str(list())

str([])

variable_name = str()

variable_name = list(str())

variable_name = str( function () )

In the below-mentioned example of try, except you can use also:

try:
	print(x)
except TypeError:
	print("Variable x is not defined")
except: print("Something else went wrong")

It will pass the x value whatever you called, and in a second method, if there is no variable to show the value, it will not bring any error like TypeError. While, in the third option, it must show “Something else went wrong.”

How to convert a tuple to string in Python

There are a number of ways to convert a tuple to a string in Python. One popular way is to use the str.join() method. This method concatenates all the elements of a tuple into a single string, separating each element with a given separator string.

Here’s an example:

tup = ('a', 'b', 'c')
sep = '-'
convert = str.join(sep, tup)
print(convert)

‘a-b-c’
If you don’t specify a separator string, the default is a single space character (‘ ‘).
