Cannot remove the right end space of the output string-CodePudding

import random
string = ''

keys = ['car', 'banana', 'groof', 'jump', 'king', 'alley']
temp = random.randint(2,3)

for i in range(temp):
    string = string   random.choice(keys)   ' '

string.strip()
print(string)

I'm just learning programming Even if you use the strip function, the space on the right end does not disappear.

What did I do wrong?

CodePudding user response：

The strip function returns the modified string but it does't modify the orignal string it only returns it which need to be stored in another string

import random
string = ''

keys = ['car', 'banana', 'groof', 'jump', 'king', 'alley']
temp = random.randint(2,3)

for i in range(temp):
    string = string   random.choice(keys)   ' '

str=string.strip()
print(str)

I suggest using a list comprehension along with string join() here:

keys = ["car", "banana", "groof", "jump", "king", "alley"]
temp = random.randint(2,3)
x = ' '.join([random.choice(keys) for i in range(temp)])
print(x)
