Making a US Heat Map?

Question

'''

perstate = df[df['State'] != '']['State'].value_counts().to_dict()

This is giving me the following: TypeError
Traceback (most recent call last)

<ipython-input-294-8cdc028c4fa9> in <module>
      7         colorscale = 'Blues',

----> 9         locations = list(perstate.keys()),
     10         locationmode = 'USA-states',
     11         text = list(perstate.values()),

TypeError: 'list' object is not callable

It was working earlier today and I haven't changed anything. Why could this be happening? I am using a notebook in Kaggle. I am trying to take the column 'State' which has the states abbreviations and I want to make a heat map.

Could you give the whole error, including the line number, as it is currently unproducible due to the nature of this problem. Most likely, you have a list e.g. a list named xyz and you are doing xyz(), which is not possible as the list is not a function. Perhaps you have variable names overlapping with function names. — RealPawPaw, Nov 17 '19 at 06:34
@RealPawPaw Just edited so it shows the whole error! Thank you — Elit Dogu, Nov 17 '19 at 06:43
@RealPawPaw I do not, I thought that would be necessary for the heatmap — Elit Dogu, Nov 17 '19 at 06:47

Based on the error, it is most likely that you have redefined the name list to a variable name, so that when you call list() to cast a variable to a type of list, the Python interpreter is actually trying to call your redefined variable as a function.

Example:

print(list("123")) # prints ["1", "2", "3"]

Now, if you define a variable called list, this happens:

list = ["redefining", "list"]
print(list("123")) # TypeError: 'list' object is not callable

Python thinks you've tried to call a variable as a function!

To resolve this issue, simply rename list to another name. The full code hasn't been posted, but you've likely redefined list at least somewhere.
