File read and write mode in python

  write the file in the python .... but it's override the old content of the file

f = open("vishal.txt",'w')

f.write("Vishal is the smart boy")

f.close()

if you want to add the text new line without the delete old content

f = open("vishal.txt",'a')

f.write("Vishal is the smart boy test\n")

f.close()

if you want to check how many character you add the file then use the following code

f = open("vishal.txt",'a')

a = f.write("Vishal is the smart boy test\n")

print(a)

f.close()

if you want read and write file at one time now you can use the following code

f = open("vishal.txt",'r+')

a = f.write("test 2\n")

content = f.read()

print(content)

f.close()
