I am having problems with the readline command in Python 2.7.
I have a text file that has 12 lines of text, each line represents a
response to a variable called star_sign that is collected via
raw_input.
However, instead of printing the line 5 it prints the first 5 letters on line 1.
Here is the program:
from sys import argv
script, zodiac = argv
prediction = open(zodiac, "r")
prompt = "> "
def welcome():
print "Welcome to your daily horoscope"
horoscope()
def horoscope():
print "I can predict your future"
print "What is your starsign?"
star_sign = raw_input(prompt)
if "Leo" in star_sign:
print prediction.readline(5)
That 5 limits the number of bytes that readline() will read to 5. I
doubt if that's what you wanted.
else:
print "You gonna die"
welcome()
I suggest instead that you replace the prediction line with
infile = open(zodiac, "r")
predictions = infile.readlines()
infile.close()
And the print line with
print predictions[5]
Notice that predictions is now a list of strings, each representing one
line of the file. They also have newlines, so you may want to strip()
them, but that's a minor issue.
