python reading and writing files

Comment

'''
You can read and write in files with open()
'r' = read
'w' = write (overwrite)
'a' = append (add)

NOTE: You can use shortened 'file.txt' if the file is in the same
directory (folder) as the code. Otherwise use full file adress.
'''

myFile = open('file.txt', 'r') # Open file in reading mode
print(myFile.read()) # Prints out file
myFile.close() # Close file

myNewFile = open('newFile.txt', 'w') # Overwrites file OR creates new file
myNewFile.write('This is a new line') # Adds line to text
myNewFile.close()

file = open('newFile.txt', 'a') # Opens existing newFile.txt
file.write('This line has been added') # Add line (without overwriting)
file.close()

write file python

Comment

# Method 1
# Use context manager "with" that automatically closes connection
with open("filename.txt", "w") as file: # xyz.txt is filename, w means write format
  file.write("hello") # write text xyz in the file
  
# Method 2
# Manually close connection
f= open("filename.txt", "w")
print(f.name) # will show what file is currently you are working with : filename.txt
print(f.mode) # will show which mode is currently in use : w
f.write("hello")
f.close()
