Python 从文本文件中打印数字行和行

Question

Im trying to read lines from a text file and print the number of the line and the line next to the number

Ive tried using enumerate but I want to find another way of doing it

the file contains :

pizza
hello
goodbye

I want to print to the screen

1-pizza
2-hello
3-goodbye

Answer 1

a simple for loop over the file:

lineCounter=0
with open('C:/t.txt') as readObj:
    lines=readObj.readlines()
    for line in lines:
        line=line.rstrip('\n')
        lineCounter += 1
        print('{}-{}'.format(lineCounter,line))
