如何获取脚本以读取文件，接受用户输入并显示用户输入中的特定行

问题描述

我正在尝试编写此代码，以便询问用户要搜索的行，然后输入该行，然后显示用户想要的行。

    import os

    f = open("input_file_lab_1.txt","r")
    allData = f.read()#3

    cleanedData = allData.split("\n")
    name = input("enter line to search\n").strip()
   
    n = 0
    while n == 0:
    for line in range(len(cleanedData)): 
        if name in cleanedData[line]: 
            print(name) 
            n = 1
        else:
            pass
    
    f.close()

不确定是否有更简单的方法。我也不断收到错误消息

  File "os1.py",line 7,in <module>

  name = input("enter line to search\n").strip()#5

AttributeError: 'int' object has no attribute 'strip'

解决方法

您可以使用以下代码段：

structure(list(diabetes_type_one = structure(c(1L,1L,2L,1L),.Label = c("No","Yes"),class = "factor"),chills = structure(c(1L,class = "factor")),row.names = c(NA,-50L),class = c("tbl_df","tbl","data.frame"))

编辑：使用import os with open("input.txt","r") as f: name = input("enter line to search\n").strip() for line in f: if name in line: print(line) break 代替@alec_djinn建议的with statement

您可能想尝试python的标准库

https://docs.python.org/3/library/linecache.html#module-linecache

import linecache
lineNumber = input("enter line to search\n").strip()
line = linecache.getline(fileName,lineNumber)
print(line)
