.read() method and looping through the io.TextIOWrapper object

Question

When line 2 is executed, the code does not run the for loop. if i removed line 2 it will run the for loop

fhand=open("file.txt")
print(fhand.read()) #line 2
lineCount=1
print("="*20)
for line in fhand:
    print("Line ",lineCount,": ",line.rstrip())
    lineCount+=1

I want to run .read() method to show the file content and aslo loop through file content line by line to add certain text

And I think you need to put in a variable:

fhand = open("file.txt")
read_fhand = fhand.readlines()
print(read_fhand)
line_count = 1
print("=" * 20)
for line in read_fhand:
    print("Line ", line_count, ": ", line.rstrip())
    line_count += 1

In python when you want to read a file you must use the code bellow:

f = open("file.txt", "r")
file = f.read()

Now the file will contain all the text file information.

To write thing into a file you must:

file = open("file.txt", "w")
file.write('text')
file.close()

you could also change the w inside the open function to an a to add text to the original text file.
