In Python, how do I read a file line
How do I read every line of a file in Python and store each line as an element in a list?
I want to read the file line by line and append each line to the end of the list.
with open(fname) as f:
content = f.readlines()
# you may also want to remove whitespace characters like `n` at the end of each line
content = [x.strip() for x in content]
我猜你的意思是list而不是数组。
See Input and Ouput:
with open('filename') as f:
lines = f.readlines()
or with stripping the newline character:
lines = [line.rstrip('n') for line in open('filename')]
Editor's note: This answer's original whitespace-stripping command, line.strip() , as implied by Janus Troelsen's comment, would remove all leading and trailing whitespace, not just the trailing n .
这比必要更明确，但是做你想要的。
with open("file.txt", "r") as ins:
array = []
for line in ins:
array.append(line)
