How to convert a tuple in a list to a normal list?-CodePudding

language: Python 3.7.0 mysql-connector-python==8.0.31

I'm working on a website and have just implemented a database. The response I'm getting from the database looks like this:

[('indigo', 'admin')]

How do I extract the two values from the tuple in a list and convert it to a list only?

Expected output:

["indigo", "admin"]

Thanks,

indigo

CodePudding user response：

You can use:

response=[('indigo', 'admin')]

data=[response[0][i] for i in [0,1]]

data

Output

['indigo', 'admin']

CodePudding user response：

Use tuple unpacking

response = [('indigo', 'admin')]
data = [*response[0]]
print(data)

Output: ['indigo', 'admin']

CodePudding user response：

you can access the first elem of the origin list [('indigo', 'admin')] (it has only one elem) to get the tuple. then use list function to convert the tuple into list.

CodePudding user response：

For this very specific example you can just access the first element of the list a = [('indigo', 'admin')] via your_tuple = a[0] which returns your_tuple = ('indigo', 'admin'). Then this tuple can be converted to a list via list(your_tuple).

In general it is better not to do these steps in between. I just put them to be more pedagogical. You get the desired result with:

list(a[0])
