Answers for "python file open and read"

python write to file

file = open(“testfile.txt”,”w”) 
 
file.write(“Hello World”) 
file.write(“This is our new text file”) 
file.write(“and this is another line.”) 
file.write(“Why? Because we can.”) 
 
file.close() 

python read file

with open("file.txt", "r") as txt_file:
  return txt_file.readlines()

read file python

document = 'document.txt'
file = open(document, 'r')
# 'r' to read.  it can be replaced with:
# 'w' to write (overwrite)
# 'a' to append (add to the end)
# 'w+' makes a new file if one does not already exist of that name
# 'a+' same as 'w+' but appends if the file does exist
# 'x' creates file for writing, but fails if file already exists

##go to beginning of document. not required but good for consistency.
file.seek(0)

##print all lines in document, except empty lines:
for line in file:
    k = line.strip() 
    print k

##close the file after you are done
file.close()


##this also works to open a file, and is more error proof:
with open(document) as filestream:
    for i in filestream:
        k = i.strip() 
        print k

python file reading

fin = open("NAME.txt", 'r')
body = fin.read().split("n")
line = fin.readline().strip()
