$($Phyton problem$)$ num$\_$soups and total$\_$allowance are read from input. A soup costs $7$ dollars.

If num$\_$soups is less than $3,$ then output 'Not enough soups.$\text{'}$

If num$\_$soups is greater than or equal to $3,$ then assign total$\_$cost with the product of num$\_$soups and $7.$

If total$\_$cost is less than or equal to total$\_$allowance, then output 'Successful purchase!$\text{'}$

Otherwise, output 'Need more money to purchase all.$\text{'}$

If total$\_$allowance is greater than or equal to $7,$ then output $\text{'}$At least one item was purchased.$\text{'}$
