convert-python

The following function converts data from a google sheet into data that a map with keys that represent the week of the year that the data is for. I'd like you to convert it to python code for me.

```typescript

export type CheckinChartData = {
  id: string,
  data: {
    x: string;
    y: number;
    checkedIn: boolean;
  }[];
}[];

export function dataToHeatmapData(data: Data): {
  [weekOfYear: string]: CheckinChartData,
} {
  const weekdayIndex = data.headers.indexOf('Day of Week');
  const timeIndex = data.headers.indexOf('time');
  const nameIndex = data.headers.indexOf('Name');
  const groupedByWeeks = groupBy(data.rows, timeIndex, getWeekNumber);
  const weeksGroupedByName = Object.keys(groupedByWeeks).reduce((groups, week) => ({
    ...groups,
    [week]: groupBy(
    groupedByWeeks[week],
    nameIndex,
    (t: string) => {
      return t;
    }
  )}), {});
  const heatMapData = Object.keys(weeksGroupedByName).reduce((groups,week) => ({
    ...groups,
    // @ts-ignore TODO
    [week]: Object.keys(weeksGroupedByName[week]).map(name => {
      // @ts-ignore TODO
      const sortedCheckins = sortCheckinByWeekday(weeksGroupedByName[week][name], weekdayIndex);
    return {
      id: name,
      data: weekdays.map((weekday, i) => {
        const checkinIndex = sortedCheckins.findIndex(checkin => checkin[weekdayIndex] === weekday);
        return {
      //@ts-ignore TODO
          x: weekday,//weeksGroupedByName[week][name].find(checkin => checkin[nameIndex] === name) ? 1 : 0,
          y: checkinIndex + 1,
          checkedIn: Boolean(checkinIndex + 1),
        }
      })
    }
  })}), {});
  return heatMapData;
}
```
