如何在阅读文件时打印某些信息？

Question

所以我在python中有这段代码：

payment = open ("paintingJobs.txt" , "r")
lines = payment.readlines()
print (lines), ["A"]

[作业] [1]

并且，我试图仅以适当的格式（不是邋）打印包含＆＃34; A＆＃34; 的文档行。 我已尝试过上面的代码，但它只是以无组织的方式打印出整个文档。

有没有办法像这样展示打印的信息：Table

Answer 1

print (lines), ["A"]不是打印包含字母A的lines的每个元素的正确语法。请尝试：

payment = open ("test.py" , "r")
lines = payment.readlines()
for line in lines:
    if "A" in line:
        print(line)
payment.close()

或者，或者，

payment = open ("test.py" , "r")
lines = payment.readlines()
print([line for line in lines if "A" in line])
payment.close()

Answer 2

您已使用with

with open("test.py" , "r") as payment
    lines = payment.readlines()
    print([line for line in lines if "A" in line])
