Removing and Replacing
As mentioned previously, there are two ways to perform removing or replacing operations. Since we used the .str
accessor two chapters ago, let's use a lambda function this time.
Swipe to start coding
-
Define a lambda function with a single argument
x
that will:-
Remove the
'$'
characters starting from the left (using the.lstrip()
method); -
Replace all blank spaces (
' '
) with empty strings (''
) (using the.replace()
method); -
Assign the function to the
rmv_rpl
variable.
-
-
Apply the
rmv_rpl
function to the'Weekly_Sales'
column using the.apply()
method and convert it to thefloat
data type.
