By default when you create a factor in R, the `NA`'s are not included as a level. Which of the following would include `NA` as a level? [see_image_1] #RStats #DataScience [TimeStamp:12032021033052] Image 1 Options:
1. `x = factor(c(1,1,2,NA))`
2. `x = factor(c(1,1,2,NA), levels = c(1,2,NA))`
3. `x = factor(c(1,1,2,"NA"))`
4. `x = factor(c(1,1,2,NA), exclude=NULL)`

#rstats users who are planning to learn #python, welcome to another edition of tweetorial.

The idea is to leverage your experience with R to explain python concepts w/o going into too much detail. For details, refer the links attached at the bottom. For today, I am covering the data types in python (except complex, binary types). R has data types: integer, double, character and boolean. Well python too has the same data types, although some names are different. In R `integer` cannot be a fractional and is written by
