Python 3.x 如何从xxx.log文件中读取所有ip地址并打印其计数？

我是JasperReports的开发者，但我的经理让我从事Python3项目，从“fileName.log”文件中读取IP地址，并希望我在一个IP多次观看我的视频时打印IP地址的计数

我对Python 3非常陌生。请帮我解决这个问题。 我的档案如下：

这里有一种方法，它涉及到将IP地址存储在字典中，这可能很有用，具体取决于您希望对数据执行的其他操作

# Read in the text file
with open('fileName.log','r') as f:
    lines = f.readlines()

data = {}
for line in lines:
    # Split the line each time a space appears, and take the first element (the IP address)
    print(line) 
    ipAddr = line.split()[0]
    if ipAddr in data:
        data[ipAddr]+=1
    else:
        data[ipAddr]=1

# Print counts of each IP address
print('   IP    Count')
for key, val in data.items():
    print(key, val)

输出：

   IP    Count
66.23.64.12 1
64.24.65.93 1
78.849.65.62 2
98.449.65.19 1
54.49.65.03 2
45.79.65.62 1

我们是否需要在这里提到文件的完整路径--->并将open（'fileName.log'，'r'）作为f：即使文件位于同一目录中？请给出有效学习Python的建议。再次感谢您。如果日志文件是从工作目录运行的，那么您不需要完整路径。嗨，Robbie，我可以从日志文件中获得IP地址的计数。为此，再次非常感谢Robbie。但他们正在询问特定时间段内活动的唯一用户的数量。没问题。这超出了这个问题的范围：您尚未定义活动。我建议再发一个问题（确保它是具体的！）：-）
