[Solved] how to remove [ , ] and single quote in class list in python 3 in single line of code? [closed]

Based on your update on what bid_data contains:

Do:

int(bid_data[6].split(':')[1].strip()) # returns an integer

Explanation:

The Python string method strip() removes excess whitespace from both ends of a string (without arguments)

Original below:

Below is based on using the input you gave, ['Quantity Required', ' 1'], to get the output of 1

If the input is ['Quantity Required', ' 1'] as a list:

>>> my_input = ['Quantity Required', ' 1']
>>> int(my_input[1].strip())
>>> 1 # is an integer

Where you can replace my_input with the literal list.

If the input is a string:

>>> string = "['Quantity Required', ' 1']"
>>> int(string.split(', ')[1].strip("'] "))
>>> 1 # is an integer
