Question

我试图使下面的代码不区分大小写，但不起作用。

如果我尝试加载确切名称!ping george的工作原理，但是如果我尝试混合使用较高或较低的!ping George机器人，则不会回复。

@bot.command(pass_context=True)
async def ping(ctx, namesList):
  with open('data.json') as json_file:
    d = json.load(json_file)
    for p in d['people']:
      if(p['Name'] in (namesList)):
        await bot.send_message(ctx.message.channel, p)

我将此if(p['Name'] in (list)):更改为if(p['Name'].lower() in (list)):

仍然无法正常工作，我认为我在这行中做错了。

根据评论编辑：

namesList # from json file names contains  with upper lower mixed.
some names contain numbers, and some names have space between name and sir name.

data.json sample

{"people": [
{"UserID": "xxxxx123", "Name": "Steve", "Sex": "Male", "age": "30"},
{"UserID": "xxxxx124", "Name": "Rachel", "Sex": "Female", "age": "25"},
{"UserID": "xxxxx125", "Name": "George", "Sex": "Male", "age": "22"} ] }

您可以创建一个set()小写名称，并在其中查找您的p["Name"]：

@bot.command(pass_context=True)
async def ping(ctx, namesList):
  # sets are better for lookups. prepare a set with all lower case names 
  setOfNamesLowerCase = set ( x.lower() for x in namesList ) # dont name lists list
  with open('data.json') as json_file:
    d = json.load(json_file)
    for p in d['people']:
      if(p['Name'].lower() in setOfNamesLowerCase ):
        await bot.send_message(ctx.message.channel, p)

集合更适合此任务，查找值为O（1），如果有重复，它们会自动减少。

在输入正确的情况下，简化了逻辑以检查它是否应该工作：

def find_tata(namesList):
    # sets are better for lookups. prepare a set with all lower case names 
    setOfNamesLowerCase = set ( x.lower() for x in namesList ) # dont name lists list
    if "tata" in setOfNamesLowerCase:
        print("Its in")
    else:
        print ("Its not")


find_tata( ["not in here","not in"])
find_tata( ["not in here","tata"])

输出：

Its not
Its in

编辑2：

import json

js = """{"people": [
    {"UserID": "xxxxx123", "Name": "Steve", "Sex": "Male", "age": "30"},
    {"UserID": "xxxxx124", "Name": "Rachel", "Sex": "Female", "age": "25"},
    {"UserID": "xxxxx125", "Name": "George", "Sex": "Male", "age": "22"} ] }"""

def ping(namesList):
    # sets are better for lookups. prepare a set with all lower case names
    setOfNamesLowerCase = set ( x.lower() for x in namesList ) # dont name lists list
    d = json.loads(js)
    for p in d['people']:
        if(p['Name'].lower() in setOfNamesLowerCase ):
            print("Doing smth for ", p["Name"]) 

ping(["rachEl", "ludwig", "ernie", "GEoRgE"])

输出：

Doing smth for  Rachel
Doing smth for  George
