Extract data (date) from a string to use as a filter in python using for loops and if statements [duplicate]

Question

I am trying to use this date information:

date_of_report = "Wednesday, May 25, 2022"

to use in an if statement that will determine which range of cell to use:

months = {
    "Jan": 31,
    "Feb": 28,
    "Mar": 31,
    "Apr": 30,
    "May": 31,
    "Jun": 30,
    "Jul": 31,
    "Aug": 31,
    "Sep": 30,
    "Oct": 31,
    "Nov": 30,
    "Dec": 31,
}

days = [
    "Sun",
    "Mon",
    "Tue",
    "Wed",
    "Thu",
    "Fri",
    "Sat",
]

weeks = [
    "Week 1",
    "Week 2",
    "Week 3",
    "Week 4",

days_of_the_month_cells = {
    "Week 1": {
        "Sun": "D6:D22",
        "Mon": "E6:E22",
        "Tue": "F6:F22",
        "Wed": "G6:G22",
        "Thu": "H6:H22",
        "Fri": "I6:I22",
        "Sat": "J6:J22",
    }, "Week 2": {
        "Sun": "D23:D39",
        "Mon": "E23:E39",
        "Tue": "F23:F39",
        "Wed": "G23:G39",
        "Thu": "H23:H39",
        "Fri": "I23:I39",
        "Sat": "J23:J39",
    }, "Week 3": {
        "Sun": "D40:D56",
        "Mon": "E40:E56",
        "Tue": "F40:F56",
        "Wed": "G40:G56",
        "Thu": "H40:H56",
        "Fri": "I40:I56",
        "Sat": "J40:J56",
    }, "Week 4": {
        "Sun": "D57:D73",
        "Mon": "E57:E73",
        "Tue": "F57:F73",
        "Wed": "G57:G73",
        "Thu": "H57:H73",
        "Fri": "I57:I73",
        "Sat": "J57:J73",
    }

}

I have this code as a base but I cannot figure out how to use an if statement to filter the information from the string I have which is a date (I beleive this would need to be done in steps)

for item in days_of_the_month_cells.values():
            for day, range in item.items():
                for index, cells in enumerate(ws[range]):
                    for cell in cells:
                        if index == 0:
                            # if ?
                            cell.value = day

any help would be appreciate

Thanks!

It is not clear what you are trying to achieve. This is supposed to be a question but I don't see any question here. — sahinakkaya

I think you are going abou this the wrong way. Just parse your date and look that up in your tables. — Jay M

I am trying to use an if statement to filter which cells are being used based on the date, how would I do that? — littlejiver

You should convert your data into a DatFrame. That will make it easier to interact with. You can convert back to JSON if you like. — NelsonGon

I never thought of use the a dateframe instead of JSON (it's late where I am :)) — littlejiver
