The syntax for combining two string values is the following.

SELECT Column1 || Column2
FROM TheTable

Technically there is not a way to do IF statements in the SQLite query language like there is in some other versions of SQL. But you can essentially do it with the CASE statement. The following statement is similar to doing an IF, ELSE IF, ELSE statement.

SELECT (CASE InRome
WHEN ‘Yes’ Then ‘Do As the Romans Do’
WHEN ‘No’ Then ‘Do As the French Do’
ELSE ‘Who knows what to do’
)

This returns a boolean value.

Similarly, you can modify the size of the text labels on the axis using cex.axis and cex.names.

barplot(x,
ylab=’Proportion’,
cex.names=2.0,
cex.axis=2.0,
cex.lab=2.0
)

def getFilesMatchingPattern(directory, nonWildCardPattern):
  fileList=os.listdir(directory)
  return [f for f in fileList if f.find(nonWildCardPattern) > -1]

ls -1R | grep .*.csv | wc -l

def parseBoolString(theString):
  return theString[0].upper()==’T’

parseBoolString(“true”)

True

parseBoolString(“false”)

False

The Individual type contains an ID, name, and email address.

Let’s say you have an ID and want to get the corresponding Individual object from the list. How would you go about doing that?

match = [ind for ind in individuals if ind.id == theID]
