What kind error in concatenation program

Question

it showing syntax error...

Answer 1

Based on your code:
https://code.sololearn.com/cxAD4v956i89/?ref=app

>>>print("First string" + ", " + "second string")
First String,Second String
>>>"spam"+"eggs"

">>>" is the immediate-mode "prompt". It means you are running Python interactively, and it is "prompting" you to type something, which it will evaluate immediately.

At that prompt, you do _not_ need to use print() because -- when a statement returns a value -- the interpreter assumes you intend (want) to print things you put there.

In scripts....like CodePlayground codes...you DO need to specify print().

print("First string" + ", " + "second string")
...Prints: First string, second string

"spam"+"eggs"
...Works in immediate mode, but for scripts use:
print("spam" + "eggs")

Calling mod to edit your post. Please use tags for search purposes and place question in post body. You meant:
>>>print("firststring" + "," + "second string")first string,sec[...]

It should be:
>>>print("1st string" + "," + " 2nd string")

I don't know what you're trying to do after that.
