with open('file_1.txt', 'r') as file :
filedata_s = file.read()
with open('file_2.txt', 'r') as file :
filedata_d = file.read()
print (filedata_s filedata_d)
檔案 1 包含 name\n ,age\n ,occupation\n etc 檔案 2 包含 Bob\n ,16\n .student\n 期望的輸出是
Name :- ‘Bob’
Age :- '16'
Occ :-'student'

如果您不關心輸出中的填充，您可以嘗試：
with open('file_1.txt', 'r') as file1,\
open('file_2.txt', 'r') as file2:
for line1, line2 in zip(file1, file2):
print(f'{line1.strip()} :- {line2.strip()}')
輸出如下所示：
name :- Bob
age :- 16
occupation :- student
如果要將其寫入新檔案：
with open('file_1.txt', 'r') as fin1,\
open('file_2.txt', 'r') as fin2,\
open('file_3.txt', 'w') as fout:
fout.writelines(
f'{line1.strip()} :- {line2.lstrip()}' for line1, line2 in zip(fin1, fin2)
)
如果您關心填充，您可以嘗試：
with open('file_1.txt', 'r') as file:
lines_1 = [line.strip() for line in file]
padding = max(map(len, lines_1))
with open('file_2.txt', 'r') as file:
for line1, line2 in zip(lines_1, file):
print(f'{line1.ljust(padding)} :- {line2.strip()}')
輸出如下所示：
name :- Bob
age :- 16
occupation :- student
在這里，您必須提前閱讀完整的第一個檔案，然后使用padding = max(map(len, lines_1))確定第一個檔案中行的最大字串長度，然后使用它來相應str.ljust()地調整輸出。
寫入新檔案：
with open('file_1.txt', 'r') as file:
lines_1 = [line.strip() for line in file]
padding = max(map(len, lines_1))
with open('file_2.txt', 'r') as fin,\
open('file_3.txt', 'w') as fout:
fout.writelines(
f'{line1.ljust(padding)} :- {line2.lstrip()}'
for line1, line2 in zip(lines_1, fin)
)
