我可能使用了错误的python术语。
我有3个整数元素的数组：月，日期和年。
但是，在连接字符串时，我无法打印每个单独的元素。
import ssl
import OpenSSL
import time
import sys
def get_SSL_Expiry_Date(host, port):
cert = ssl.get_server_certificate((host, 443))
x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
raw_date = x509.get_notAfter()
decoded_date = raw_date.decode("utf-8")
dexpires = time.strptime(decoded_date, "%Y%m%d%H%M%Sz")
bes = dexpires.tm_mon,dexpires.tm_mday,dexpires.tm_year
print (bes)
#print(bes[0]+"/"+bes[1]+"/"+bes[2])
domain = sys.argv[1]
port = 443
get_SSL_Expiry_Date(domain, port)
如果取消注释第14行，则会出现错误：
TypeError: unsupported operand type(s) for +: 'int' and 'str'
我正在尝试以以下格式（所有字符串）获取日期：Month/Date/Year。
我在做什么错了？

您可以使用Python的format()方法来处理它（也更加简洁）：
print("{0}/{1}/{2}".format(bes[0],bes[1],bes[2]))
...或进一步简化（感谢Anton）
print("{0}/{1}/{2}".format(*bes))

首先，您必须将int值转换为字符串，而不仅仅是使它们凹入。
您可以使用str()内置方法
print(str(bes[0])+"/"+ str(bes[1])+"/"+ str(bes[2])) #convert int to str first.

只需使用：

通常，python模块通常包含各种重新格式化功能，您无需重新发明它们。
示例：
print(time.strftime("%m/%d/%y",dexpires))
