Question

I’m having trouble using python to write strings into a file:
(what I’m trying to do is using python to generate some C programs)
The code I have is the following:

filename = "test.txt"
i = 0
string = "image"
tempstr = ""
average1 = "average"
average2 = "average*average"
output = ""
FILE = open(filename,"w")
while i < 20:
    j = 0
    output = "square_sum = square_sum + "
    while j < 20:        
        tempstr = string + "_" + str(i) + "_" + str(j)        
        output = output + tempstr + "*" + tempstr + " + " + average2 + " - 2*" + average1 + "*" + tempstr        
        if j != 19:        
            output = output + " + "
        if j == 19:
            output = output + ";"        
        j = j + 1
    output = output + "\n"
    i = i + 1
    print(output)
    FILE.writelines(output)    
FILE.close

The print gives me correct output, but the FILE has last line missing and some of the second last line missing. What’s the problem in writing strings into file?

Thank you!

Probably help if you called the method…

FILE.close()
