Python 字符串比较似乎不起作用

Question

首先，我从文本文件中提取分配给 clientID 的强度，一旦获得该强度，我将其存储为 clientIntensityResult，然后根据它是否等于高或中等，它应该打印出相应的列表，但我在 if 语句中的比较似乎不起作用？我已将其更改为 x = 1, if x == 1: 这有效，但在这个字符串比较中我缺少一些东西？

def clientSelect():
    clientIntensity = open("clientIntensity.txt", "r") #opens file

    high = ["Running", "Swimming", "Aerobics", "Football", "Tennis"]
    moderate = ["Walking", "Hiking", "Cleaning", "Skateboarding", "Basketball"]

    searchId = input("Please enter a clientID (ffsss): ") #search string

    for line in clientIntensity:
        if re.match(searchId, line):
            clientIntensityResult = (line[6:])
            print ("Client intensity is: ", clientIntensityResult)

            if clientIntensityResult == "High":
                print (high)
            elif clientIntensityResult == "Moderate":
                print (moderate)
            else:
                print ("Nothing found")

Answer 1

您将变量定义为

clientIntensityResult = (line[6:])

由于您是逐行迭代，因此每个字符串末尾都会有一个 '\n' 。你可以这样做

clientIntensityResult = line.strip()[6:]

那么剩下的就应该可以工作了。
