替换字典中的值

Question

我有一个python字典，我想替换其中的值。

dict = {
"blocks": [
{
"type": "section",
"text": {
"type": "mrkdwn",
"text": ":{circle}: <{log_url}| {task}>"
}
},
{
"type": "divider"
},
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": "*Dag Name:* {dag}"
},
{
"type": "mrkdwn",
"text": "*Execution Time:* {exec_time} UTC"
}
]
}
]
}

我想替换{}中包含的值，如circle、log_url等。

我尝试了以下方法，将其转换为字符串表示，但我遇到了异常。

dict = """
{
"blocks": [
{
"type": "section",
"text": {
"type": "mrkdwn",
"text": ":{circle}: <{log_url}| {task}>"
}
},
{
"type": "divider"
},
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": "*Dag Name:* {dag}"
},
{
"type": "mrkdwn",
"text": "*Execution Time:* {exec_time} UTC"
}
]
}
]
}""".format(task="a",
dag="b",
exec_time="10",
log_url="url",
circle=circle)

但它给了我错误。错误-'\n\t"块"。。。KeyError：'\n\t"块">

我该如何解决？

完整代码：

import json
import requests

def send_slack_success_metadata_alert():
circle = 'green-tick'
template = """{
"blocks": [
{
"type": "section",
"text": {
"type": "mrkdwn",
"text": ":{circle}: <{log_url}| {task}>"
}
},
{
"type": "divider"
},
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": "*Dag Name:* {dag}"
},
{
"type": "mrkdwn",
"text": "*Execution Time:* {exec_time} UTC"
}
]
}
]
}""".format(
task="T1",
dag="ID",
exec_time="10",
log_url="dummyurl",
circle=circle
)
print(template)
send_alert("http://localhost:80",template)
def send_alert(url, message):
requests.post(url=url, data=json.dumps({'text': message}),
headers={'Content-type': 'application/json'})
if __name__ == "__main__":
print(send_slack_success_metadata_alert())

您需要在以后的步骤中设置值吗？或者f字符串是你的解决方案吗？

task="a"
dag="b"
exec_time="10"
log_url="url"
circle=circle
dict = {
"blocks": [
{
"type": "section",
"text": {
"type": "mrkdwn",
"text": f":{circle}: <{log_url}| {task}>"
}
},
{
"type": "divider"
},
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": f"*Dag Name:* {dag}"
},
{
"type": "mrkdwn",
"text": f"*Execution Time:* {exec_time} UTC"
}
]
}
]
}
