如何使用python脚本获得以下输出：

 Petar Petrovic 32 USA
 Nick Cave 22 Brasil

到目前为止，我有这个

#!/bin/python
import sys
import os
import re   
with open ("output.txt", "r") as myfile:
data=myfile.read()

我读到我可能会使用字典但不知道如何实现它。

Answer 1

您可以使用正则表达式：

import re

people = re.findall(r'\bFirst name: (\S+)\s+Last Name: (\S+)\s+Age: (\d+)\s+Country: (\S+)', data)
for personinfo in people:
    print(' '.join(personinfo))

输出：

Petar Petrovic 32 USA
Nick Cave 22 Brasil

Answer 2

@ Aran-Fey肯定有一个更简单的答案，但是因为我已经写了它的另一个选择：

with open ("output.txt", "r") as myfile:
    output = []
    for line in myfile:
        if ":" in line:
            output.append(line.split(":")[1].strip())

to_print = []
for index, elem in enumerate(output):
    if ((index+1)%5 == 0):
        print(" ".join(to_print))
        to_print = []
    to_print.append(elem)

print(" ".join(to_print))

Python-在特定字符后提取值并将其存储在列中
