I have a file comprising two columns, i.e.,
I have 2 CSV files: ‘Data’ and ‘Mapping’:
I’m used to bringing data in and out of Python using CSV files, but there are obvious challenges to this. Are there simple ways to store a dictionary (or sets of dictionaries) in a JSON or pickle file?
I’m trying to take a file that looks like this:
PDF = ‘C:/Users/user/Desktop/File_%s.pdf’ %item
For instance, I’ve tried things like mydict = {'funcList1': [foo(),bar(),goo()], 'funcList2': [foo(),goo(),bar()], which doesn’t work.
I am a big fan of using dictionaries to format strings. It helps me read the string format I am using as well as let me take advantage of existing dictionaries. For example:
I receive a dictionary as input, and would like to to return a dictionary whose keys will be the input’s values and whose value will be the corresponding input keys. Values are unique. For example, say my input is: a = dict() a['one']=1 a['two']=2 I would like my output to be: {1: 'one', 2: 'two'} … Read more
