python – 如何从文件中打印特定行

发布时间：2020-12-20 12:10:28 所属栏目：Python 来源：网络整理

导读：我正在尝试从“Scores”文件中打印一个特定的行,这是选项B.这是我的代码： print("Option A: Show all scoresnOption B: Show a recordnOption Q: Quit")decision = input("Enter A,B,C or Q: ")myFile = open("Scores.txt","rt")if decision == "A": reco

我正在尝试从“Scores”文件中打印一个特定的行,这是选项B.这是我的代码：

print("Option A: Show all scoresnOption B: Show a recordnOption Q: Quit")
decision = input("Enter A,B,C or Q: ")
myFile = open("Scores.txt","rt")
if decision == "A":
    record = myFile.read()
    print(record)
    myFile.close()
elif decision == "B" or decision == "b":
    playerName = input("Enter a player name to view their scores: ")
    record = myFile.read()
    answer = record.find(playerName)
    for line in answer:
        print(line)
elif decision == "Q" or decision == "q":
    exit

我选择了选项B,然后我输入了一个持有玩家得分的玩家名称,但它会抛出此错误消息：

line 12,in <module>
for line in answer():
TypeError: 'int' object is not callable

解决方法

我身边的几美分：

file = open("file")
lines = file.readlines()
for line in lines:
    if playername in line:
        print line

file.close()

希望它有效！
