How to show cell output in the "app" view?

[hopezh]

I have the following code that prints out the keys in a dict.

May I ask how to show these output in the app view?

I've tried to replace the print line in the for loop with mo.md(f"key : {key}"), and it's not showing anything.

Ok, seems one way is to put all that I want to show in the app view in a multi-line string, using the line breaker \n for each item, and put this string variable at the end of the cell.

BTW, mo.md() will flattern the multi-line string into one line, and I don't know why...

top_level_keys = 'Top level keys: \n'

cnt = 0
for key, val in json_data.items():
    # print('key', '{:02d}'.format(cnt), ':', key)
    top_level_keys += '\t' + 'key ' + '{:02d}'.format(cnt) + ' : ' + key + '\n'
    cnt +=1

top_level_keys

Anayway I still want to ask if there is a more efficient, or marimo way, to show the output of a cell, no matter how many lines, in a text box in the app view?

Ok, there is the mo.ui.text_area() function to show multi-line string in a text box.

top_level_keys = 'Top level keys: \n'

cnt = 0
for key, val in json_data.items():
    # print('key', '{:02d}'.format(cnt), ':', key)
    top_level_keys += '\t' + 'key ' + '{:02d}'.format(cnt) + ' : ' + key + '\n'
    cnt +=1

mo.ui.text_area(top_level_keys)
