python - 在python中将行号添加到字符串中

Question

我有一个以下格式的文本文件:

"This is record #1"
"This is record #2"
"This is record #3"

我需要以下格式的输出:

Line number (1) --\t-- "This is Record # 1"
2-- \t-- "This is Record # 2"
3-- \t-- "This is Record # 3" 

当前代码:

f = open("C:\input.txt","r")
write_file = open("C:\output.txt","r+")
while True:
    line = f.readline()
    write_file.write(line)
    if not line : break
write_file.close()
f.close()

Answer 1

尝试以这种方式遍历您的文件:

f = open('workfile', 'r')
for num,line in enumerate(f):
    print(num+" "+line)
