Need Help With Python File Handling

The picture shows the scenario and what I’m trying to achieve with my code.

gs = open("garagesales.txt", "r")
newFile = open("new.txt", "w")
newFileRecords = 0

for proLitSales in gs:
    if float(proLitSales) > 100000:
        newFile.write(proLitSales + "\n")
        newFileRecords += 1
gs.close()
print("Total number of records written to newFile.txt is:", newFileRecords)
newFile.close()
newFile = open("new.txt", "r")
print(newFile.read())
newFile.close()

If someone can provide some corrections or examples that would be great, thanks.
