在python

Question

我在做一个简单的比较字符串，结果为假。

我认为它是在行尾比较“ \ n”字符，但不确定。

有趣的是，当您比较每个列表的姓氏时，它的确会抛出TRUE。

PSEUDO

  

  

1. 创建循环以检查对象列表中的每个文件

  

2. 检查男孩名字列表。.boys.txt

  
3. 检查女孩名字列表.. girls.txt
  
4. 如果在列表和索引位置（不允许使用切片），则输出结果
  

这是代码 boys.txt

john
paul
andrew
judas
archie
scot

girls.txt

cassie
sam
josie
nadine
cathy

nameSearch.py​​

def read_list(fileToOpen):
    thisFile = fileToOpen + ".txt"
    filez = open(thisFile, "r")    
    names = filez.readlines()    
    filez.close()

    return names

def findName(name, nameList):
    count = 0
    pos = -1

    for thisName in nameList:
        print("Comparing", name, "to", thisName)

        if name == thisName:
            print (name, "has been found !!!")
            pos = count
        else:
            print(name, "does not compare to", thisName)
            count += 1

    return

filesList = ["boys", "girls"]

name = input("What is the name of the child ? ")

for thisFile in filesList:
    nameList = read_list(thisFile)
    result = findName(name,nameList)

Answer 1

解决方案很容易，我更新了

def findName(name, nameList):
    count = 0
    pos = -1

    for thisName in nameList:
        print("Comparing", name, "to", thisName)
        aName = thisName.strip("\n")  ## <-- added this line
        if name == aName:
            print (name, "has been found !!!")
            pos = count
        else:
            print(name, "does not compare to", aName)
            count += 1

    return
