How can I use less lines of code in this code? (It's from the famous rice chess fable)

I want to avoid recursion, but I'm happy to use for loops. I'm writing to file for a reason, so it must stay.

count =1
b = 1
total = 0
while count <65:

 b = b*2
 total = total +b
 print ("Square number is:",count)
 print ("rice on that square",b)
 print ("total so far:", total)
 count +=1
 f = open("rice.csv", "a")
 f.write(str(b)+ "\n")
 f.close()

print ("all together that  ",total,"grains of rice")

kg = total/33000

cost = kg * 1.20

print ("that is £", cost,", thank you very much!")

One thing you could do is to use a context manager to open the file. That way it autimatically closes itself.

with open("rice.csv", "a") as file:
    file.write(str(b)+ "\n")

Note: I changed the mode for open to w as you are opening it only once.

total = 0
with open("rice1.csv", 'w') as f:
    for i in range(64):
        b = 2**(i+1)
        total += b
        print("Square number is:", i+1)
        print("rice on that square",b)
        print("total so far:", total)
        f.write(str(b)+ "\n")

print ("all together that  ",total,"grains of rice")

cost = total/33000  * 1.20

print ("that is £", cost,", thank you very much!")
