invalid literal for int with base 10

Question

In order to create a program which can read the file and the starting line on the file is not empty or blank, which further enables the next four lines to be deciphered, what must one do? The calculations are performed on the lines and then the next line is readable. However, if that line isn’t empty, it still continues. However, this error persists:

ValueError: invalid literal for int() with base 10
 

Despite being able to understand and read the line at the start, the process of converting it to an integer is not working for me. What can I do to fix this problem?

file_to_read = raw_input("Enter file name of tests (empty string to end program):") 
try: infile = open(file_to_read, 'r') 
while file_to_read != " ": 
file_to_write = raw_input("Enter output file name (.csv will be appended to it):") 
file_to_write = file_to_write + ".csv" 
outfile = open(file_to_write, "w") 
readings = (infile.readline()) 
print readings 
while readings != 0: 
global count 
readings = int(readings) 
minimum = (infile.readline()) 
maximum = (infile.readline())

Answer 1

In order to solve this problem, one must use the following lines of code:-
 

>>> int('55063.000000') 
Traceback (most recent call last): 
File "<stdin>", line 1, in <module> 
ValueError: invalid literal for int() with base 10: '55063.000000'

Which brings the user to this and must be used to avoid the problem of non conversion to the integer:-
 

>>> int(float('55063.000000')) 55063
