Python從輸入文件讀取行並將其寫回文件

Question

我想逐行讀取輸入文件，然后修改一行並將更改寫回同一文件

問題是，回寫后，我失去了返回該行的權限，並且所有數據都放在一行中

open(bludescFilePath, 'a+') as blu:

blu_file_in_lines = blu.readlines()

for line in blu_file_in_lines:
                    if "Length" in line:
                        blu_file_in_lines[13] = line.replace("0x8000",str(size))

 with open(bludescFilePath, 'w') as blu:
                blu.write(str(blu_file_in_lines))

好的，缺少的是for循環。

with open(bludescFilePath, 'w') as blu:
    for line in blu_file_in_lines:
        blu.write(str(line))
