file = open("D:\\myfiles\python.txt", "r")
print(file.read())3.Reading Files in Python:
i. Read one line of the file:
Syntax:
file = open("python.txt", "r")
print(file.readline())ii. Read two lines of the file:
Syntax:
file = open("python.txt", "r")
print(file.readline())
print(file.readline())iii. Read the file line by line :
Syntax:
file = open("python.txt", "r")
for a in file:
print(a)4. Writing to Files in Python:
i. Append content to the file:
Syntax:
file = open("python.txt", "a")
file.write("Now the file has more content!")
file.close()ii. Overwrite content to the file:
Syntax:
file = open("python.txt", "w")
file.write("Previous content deleted!")
file.close()5. Closing Files in Python:
Syntax:
file = open("python.txt", "r")
print(file.readline())
file.close()6. Deleting Files in Python:
Syntax:
import os
if os.path.exists("python.txt"):
os.remove("python.txt")
else:
print("The file does not exist")
