How do i join 2 strings the right way-CodePudding

My problem is that this code only prints out "a"

print(str(random.randint(1, 2)).join(str("a")))

CodePudding user response：

join is used to concatenate elements of an iterable. What you need is the operator, so:

print(str(random.randint(1, 2)) "a")

You also don't need to cast "a" to string (it is a string already).

CodePudding user response：

.join() does not do what you think it does. What I think you actually want is string concatenation, which is done using the operator. Also, the str() around "a" is unnecessary as it is already a string.

Here is the corrected code:

import random
print(str(random.randint(1, 2))   "a")

CodePudding user response：

i didn't get what actually but: a='test'
print(str(random.randint(1, 2)).join(str(" a")))'
output : t2e2s2t

CodePudding user response：

I would use string formatting:

>>> import random

>>> '{}a'.format(random.randint(1, 2))
'1a'
