python open file

with open('filename', 'a') as f: # able to append data to file
	f.write(var1) # Were var1 is some variable you have set previously
	f.write('data') 
	f.close() # You can add this but it is not mandatory 

with open('filename', 'r') as f: # able to read data from file ( also is the default mode when opening a file in python)

with open('filename', 'x') as f: # Creates new file, if it already exists it will cause it to fail

with open('filename', 't') as f: # opens the file in text mode (also is defualt)

with open('filename', 'b') as f: # Use if your file will contain binary data
  
with open('filename', 'w') as f: # Open file with ability to write, will also create the file if it does not exist (if it exists will cause it to fail)
  
with open('filename', '+') as f: # Opens file with reading and writing

# You can combine these as you like with the + for reading and writing

python open file

fileName = "file_name.txt" #Here you need to write the file name as a string

openLike = "" #Here you need to write how do you want to open the file:
#"w": Write, "r": Read
openedFile = open("file_name.txt", openLike) #Here you open the file
fileText = openedFile.read() #This read all the file
openedFile.close() #Close the file
print(fileText) # Prints the file text

python file open

#there are many modes you can open files in. r means read.
file = open('C:Usersyournamefilesfile.txt','r')
text = file.read()

#you can write a string to it, too!
file = open('C:Usersyournamefilesfile.txt','w')
file.write('This is a typical string')

#don't forget to close it afterwards!
file.close()

open file python

# Open function to open the file "MyFile1.txt" 
# (same directory) in append mode and
file1 = open("MyFile.txt","a")
  
# store its reference in the variable file1 
# and "MyFile2.txt" in D:Text in file2
file2 = open(r"D:TextMyFile2.txt","w+")

Open file with python

import os
my_computer = os.startfile("C:") # here c drive open this variable
print(my_computer)

opening files in python

f = open("test.txt", mode='r', encoding='utf-8')

file open in python

with open("cars.txt") as cars:   #open cars.txt file declaration  cars variable then assign cars.txt data
  	blue_cars = cars.read() #read cars.txt data and assign to blue_cars
    #advantage using this, implicitly applied cars.close() method

 ------Similar to ----
cars = open("cars.txt")
blue_cars = cars.read()
cars.close()

open file in python

import os

os.system('filename.extension')
