我有一个包含以下数据的文件(file.txt):
192.168.10.1/16, 22, 3265, tcp
172.144.32,2/34, 22, 21, udp
10.128.16.234/8, 0, 20, icmp
我需要按cloumn[0]、cloumn[1]和column[2]对其进行排序
我有一个包含以下数据的文件(file.txt):
192.168.10.1/16, 22, 3265, tcp
172.144.32,2/34, 22, 21, udp
10.128.16.234/8, 0, 20, icmp
我需要按cloumn[0]、cloumn[1]和column[2]对其进行排序
我的解决方案是创建一个元组列表(每行一个元组),如下所示:
(data_in_column_of_interest, entire_line)
其中data_in_column_of_interest
是任何数据类型并且entire_line
是字符串。
然后对这个列表进行排序:
def sortLinesByColumn(readable, column, columnt_type):
"""Returns a list of strings (lines in readable file) in sorted order (based on column)"""
lines = []
for line in readable:
# get the element in column based on which the lines are to be sorted
column_element= columnt_type(line.split(',')[column-1])
lines.append((column_element, line))
lines.sort()
return [x[1] for x in lines]
with open('G:/Ftest/data.txt') as f:
# sort the lines based on column 1, and column 1 is type int
sorted_lines = sortLinesByColumn(f, 1, int)
for l in sorted_lines:
print(l)
输入:文件包含:
1, Bob, 123
5, Mary, 112
0, Allen, 2421
1, lucy, 341
输出:字符串列表:
0, Allen, 2421
1, Bob, 123
1, lucy, 341
5, Mary, 112
