Log processing 1
Task:Every three rows of records are a piece of log. Organize the log into a structured file.
Python
| 1 | import pandas as pd |
| 2 | import numpy as np |
| 3 | log_file = ‘E://txt//access_log.txt’ |
| 4 | log_info = pd.read_csv(log_file,header=None) |
| 5 | log_g=log_info.groupby(log_info.index//3) |
| 6 | rec_list = [] |
| 7 | for i,g in log_g: |
| 8 | rec = g.values.reshape(1*3) |
| 9 | rec[1] = rec[1].split(":")[-1].replace("#","") |
| 10 | rec="\t".join(rec) |
| 11 | rec = np.array(rec.split("\t")) |
| 12 | rec = rec[[6,7,0,1,3,4,8,5]] |
| 13 | rec_list.append(rec) |
| 14 | rec_df = pd.DataFrame(rec_list,columns=["USERID","UNAME","IP","TIME","URL","BROWER","LOCATION","module"]) |
| 15 | print(rec_df) |

| 4 | =A3.(~.(_1).concat("\t").array("\t")) | |

With the mechanism of grouping by row number, you can process one group of data every time in loop, simplifying the difficulty.
