How to extract a single word from a text file

[bowlofred]

Your first error is because you've set "x" to be the return value of print(). print() has no return value, so "x" becomes None. What did you want x to be?

readlines() reads all the lines in the file. If you only have one line, you might prefer readline().

If you want to split the line (which was previously "betalines[0]"), you'd do betalines[0].split().

beta = open('beta.txt', 'rt')
betaline = beta.readline()
y = betaline.split()[3]
print(y)

Output:
928.2M,
