如何仅打印第三行上的日期

Answer 1

这将有助于您：

f = open("D:\\Test.txt","r")
third_line = f.readlines()[2].strip()
f.close()
print(third_line)

输出：

3,04/09/15,18:00,Ripley,Billy Casper,Y,Billy Casper

下面是一个例子：

with open("./records.txt") as f:
    lines = f.readlines()
    for i, line in enumerate(lines):
        if i==3:
            print(line)
