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

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

CodePudding user response：

change it from fhand.read() to fhand.readlines() then you will get list of lines

fhand=open("file.txt")
print(fhand.readlines()) #change it to readlines()
lineCount=1
print("="*20)
for line in fhand:
    print("Line ",lineCount,": ",line.rstrip())
    lineCount =1

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
