如何从文件中打印特定行 [英] How to print a specific line from a file

问题描述

我正在尝试从文件分数"(即选项B)中打印一行.这是我的代码:

I am trying to print a specific line from the file "Scores", which is option B. This is my code:

print("Option A: Show all scores\nOption B: Show a record\nOption 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，然后输入了保留该球员得分的球员名称，但是会抛出以下错误消息:

I went for Option B, then I entered a player name that holds the score of the player, but it throws this error message:

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

推荐答案

从我这边走了几分钱:

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

file.close()

希望它能起作用！
