how to write data in file python code example

Example 1: 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()

Example 2: python append to file

with open(filename, "a+") as f:
  f.write('Hello World')

Example 3: python write to file

# open a file you can use the function open
file = open("myFile.txt", "w")
#here we have "open", and that's the main function
# that opens the file, next we have 2 arguments
# FILENAME and OPENING MODE
# in the filename argument you just have to write the file's location
# or if the script is in that location just write the filename
# in the opening mode you have to write in which mode you want
# to open your file, i'll list some here:
# "w" for writing to a file
# "r" for reading to a file
# "r+" for both reading and writing
# "a" to append to a file
#to write to the file use "file.write"
file.write("This has been written by a program")
#and finally to close the file when you're done with it
file.close()
# hope this helped and remember that in "w" mode it
#deletes the content of the file and replaces
# it with a new one, if you want to add something
# to a file use "a" mode

Example 4: how to write a python variable to a file

#use pickle

import pickle
dict = {'one': 1, 'two': 2}
file = open('dump.txt', 'w')
pickle.dump(dict, file)
file.close()

#and to read it again
file = open('dump.txt', 'r')
dict = pickle.load(file)
