this is sample {data1}
this one is {data2}
again {data1}
我有这段代码可以将文件行读入列表并打印列表:
data1 = 'line 1'
data2 = 'line 2'
with open('data.txt') as file:
lines = file.read().splitlines()
print(lines)
输出为:
['this is sample {data1}', 'this one is {data2}', 'again {data1}']
现在,我如何用变量的值替换变量,并使其像:
['this is sample line 1', 'this one is line 2', 'again line 1']
