Python Split Output在方括号中

Question

I have code that looks like this:

import re
activity = "Basketball - Girls 9th"
activity = re.sub(r'\s', ' ', activity).split('-')
activity = str(activity [1:2]) + str(activity [0:1])
print("".join(activity))

I want the output to look like Girl's 9th Basketball , but the current output when printed is [' Girls 9th']['Basketball '] I want to get rid of the square brackets. I know I can simply trim it, but I would rather know how to do it right.

Answer 1

You are stringyfying the lists which is the same as using print(someList) - it is the representation of a list wich puts the [] around it.

import re
activity = "Basketball - Girls 9th"
activity = re.sub(r'\s', ' ', activity).split('-')
activity =  activity [1:2]  + [" "] +  activity [0:1] # reorders and reassignes list

print("".join(activity))

You could consider adding a step:

# remove empty list items and remove trailing/leading strings
cleaned = [x.strip() for x in activity if x.strip() != ""]

print(" ".join(cleaned)) # put a space between each list item

This just resorts the lists and adds the needed space item in between so you output fits.

Answer 2

You're almost there. When you use .join on a list it creates a string so you can omit that step.

import re
activity = "Basketball - Girls 9th"
activity = re.sub(r'\s', ' ', activity).split('-')
activity = activity[1:2] + activity[0:1]
print(" ".join(activity))

Answer 3

您可以在一行中解决它：

new_activity = ' '.join(activity.split(' - ')[::-1])

Answer 4

You can try something like this:

import re
activity = "Basketball - Girls 9th"
activity = re.sub(r'\s', ' ', activity).split('-')
activity = str(activity [1:2][0]).strip() + ' ' + str(activity [0:1][0])
print(activity)

output:

Girls 9th Basketball
