Python問題，當bucket_name與bucket串列中的專案匹配時，第一個if陳述句沒有運行-有解無憂

#1 激活 Boto 以供使用并將其定向到 s3 存盤

import boto3
s3 = boto3.resource('s3')

#2 Python 要求用戶創建存盤桶名稱

  bucket_name = input("Select a bucket name (must be all lowercase).  ")

#3 Python 在 s3 中收集存盤桶名稱并列印串列

for bucket in s3.buckets.all():
    print(bucket.name)
bucket = list(s3.buckets.all())

#4 使用 s3 檢查 bucket_name 與名稱是否匹配，如果匹配則通知他們，并要求創建另一個名稱。如果名稱不是，它會創建一個具有新唯一名稱的新存盤桶。

if bucket_name in bucket:
    print("The name you selected is already taken, please choose a different name")
    bucket_name = input('Select another bucket name (must be all lowercase).  ')
else:
    print('Your new bucket is named',bucket_name,"!")
    def create_bucket():
        s3_client = boto3.client('s3')
        s3_client.create_bucket(Bucket=bucket_name)
    create_bucket()

這應該有效：

import boto3

def create_bucket(bucket_name):
    s3_client = boto3.client('s3')
    s3_client.create_bucket(Bucket=bucket_name)

bucket_name = input("Select a bucket name (must be all lowercase).")

s3 = boto3.resource('s3')
all_buckets = list(s3.buckets.all())

if bucket_name in all_buckets:
    print("The name you selected is already taken, please choose a different name")
    bucket_name = input('Select another bucket name (must be all lowercase).  ')
else:
    print('Your new bucket is named',bucket_name,"!")
    create_bucket(bucket_name)

這將運行并使用您的邏輯搜索每個輸入的名稱，直到您退出。輸入將自動降低.lower()。

import boto3
s3 = boto3.resource('s3')
bucketNames = [bucket.name for bucket in s3.buckets.all()]

def create_bucket(bucket_name):
    s3_client = boto3.client('s3')
    s3_client.create_bucket(Bucket=bucket_name)

while True:
    bucket_name = input("Write a bucket name (q to quit):  ").lower()
    if bucket_name not in bucketNames:
        print(f'Your new bucket is named {bucket_name}!')
        create_bucket(bucket_name)
    else:
        print("The name you wrote is already taken, try a different name")
        bucket_name = input('Write a bucket name (q to quit):  ').lower()
    if bucket_name == "q" or bucket_name == "quit":
        break

首先使用以下代碼提取所有存盤桶名稱。

import boto3
s3 = boto3.resource('s3')

bucket_name = input("Select a bucket name (must be all lowercase).  ")

all_buckets = [bucket.name.lower() for bucket in s3.buckets.all()]

現在檢查其中是否存在 bucket_name。

if bucket_name in all_buckets:
    print("The name you selected is already taken, please choose a different name")
    # Your rest of the logic goes here.
