I've been trying to have this data write to the "scenario_out.txt" file. However, when I run the code I do not any get errors but my text file does come out to empty, so no data was ever put into the file. . I'm reviewing my notes but I don't see where I went wrong.

I've tied some bool variable to use as a flag , but still no luck.
At the moment, you're just printing your output to the console, rather than actually saving it to the file.
You probably want something like
if save_to_file == True:
output = (
' Year : ' + str(scen_year) +
'\n Age : ' + str(age) +
'\n Start Bal : ' + (format(s_bal, ',.2f')) +
'\n Start Bal PV : ' + (format(bal_pv, ',.2f')) +
'\n Invest Gains : ' + (format(inv_gains, ',.2f')) +
'\n Ann Savings : ' + (format(ann_savings,',.2f')) +
'\n SS Payment : ' + (format(ss_payment, ',.2f')) +
'\n Major Inc : ' + (format(major_inc, ',.2f')) +
'\n Major Exp : ' + (format(major_exp, ',.2f')) +
'\n Tax Rate : ' + (format(tax_rate, '.2%')) +
'\n Targ Ret Spend : ' + (format(tar_ret_spend, ',.2f')) +
'\n Net Ret Spend : ' + (format(net_ret_spend, ',.2f')) +
'\n Ret Pre-tax Spend : ' + (format(ret_pre_tax_spend, ',.2f')) +
'\n Taxes : ' + (format(taxes, ',.2f')) +
'\n End Bal : ' + (format(end_bal, ',.2f'))
)
file_object.write(output)
This creates a big string of your output data, then writes it to your file object.
