I am trying to create a function which would take a list and be able to count the number of ints floats and str in that list.

output should be:

list =

freq = countDataTypes(list)

print(freq)

[2,1,1]

any help would be greatly appreciated

so far:

```
>>> def countDataTypes(aList):
rtnlist = [0,0,0]
for x in aList:
if type(x) is string:
```

the rtnlist[0,0,0] is what this will return. if there are 2 ints, 1 float and 0 str then rtnlist[2,1,0]
