我想打开一个文件,只需返回所述文件的内容,每行以行号开头.
假设其内容a是假设的
a
b
c
我希望结果如此
1: a
2: b
3: c
我有点卡住,尝试枚举,但它没有给我所需的格式.
适用于Uni,但仅限于练习测试.
一些试验代码证明我不知道我在做什么/从哪里开始
def print_numbered_lines(filename):
"""returns the infile data with a line number infront of the contents"""
in_file = open(filename, 'r').readlines()
list_1 = []
for line in in_file:
for item in line:
item.index(item)
list_1.append(item)
return list_1
def print_numbered_lines(filename):
"""returns the infile data with a line number infront of the contents"""
in_file = open(filename, 'r').readlines()
result = []
for i in in_file:
result.append(enumerate(i))
return result
