Suppose I have some data like:
data[0] = ['I want to make everything lowercase']
data[1] = ['How Do I Do It']
data[2] = ['With A Large DataSet']
How do I repeatedly call the lower() function on all the elements of data
, to make all the of strings in lowercase?
I have tried {k.lower(): v for k, v in data.items()}
, but I get an error saying that 'list' object has no attribute 'items'
.
I have also tried using .lower()
and it is giving me the same AtrributeError
.
if your list data like this:
data = ['I want to make everything lowercase', '', '']
data = [k.lower() for k in data]
if your list data is a list of string list:
data = [['I want to make everything lowercase'], ['']]
data = [[k.lower()] for l in data for k in l]
the fact is that list don't has attribute 'items'
