如何編寫具有特定格式的文本文件？

Question

我的初始數據是這個，但是我想像這樣的數據那樣寫成“ cat_id | content”格式的數據

5 Name NRIC DOB 1932.11.26 Race Chinese Sex Female ND - PATIENT CARE RECORD  
4 Name NRIC DOB 1933.05.01 Race Chinese Sex Male PM - PATIENT CARE RECORD 

我希望以這種格式在文本文件中寫入所需的格式：

cat_id|content
5|Name NRIC DOB 1932.11.26 Race Chinese Sex Female ND - PATIENT CARE RECORD  
4|Name NRIC DOB 1933.05.01 Race Chinese Sex Male PM - PATIENT CARE RECORD 

我這樣做是因為forloop中有大量內容（僅供您理解）

text_file = open("ED_Notes.txt", 'w')
for item in arr_cat:
    text_file.write("%s\n" % item)

請幫忙謝謝！！ :)

Answer 1

這應該有所幫助。

演示：

with open(filename) as infile:
    toWrite = ["|".join(line.split(" ", 1)) for line in infile]     #Iterate each line and split by first space and the join by |

with open(filename, "w") as outfile:          #Write back to file. 
    for line in toWrite:
        outfile.write(line)

輸出：

5|Name NRIC DOB 1932.11.26 Race Chinese Sex Female ND - PATIENT CARE RECORD  
4|Name NRIC DOB 1933.05.01 Race Chinese Sex Male PM - PATIENT CARE RECORD 

Answer 2

我認為您可以使用正則表達式執行此操作。

我會嘗試這樣的事情：

import re

text_file = open("ED_Notes.txt", 'w')

for item in arr_cat:
    m = re.search("([0-9]) ([a-zA-Z].*)",item)
    text_file.write(m.group(1)+"|"+m.group(2))
text_file.close()

對不起，我很着急，所以我沒有測試
