Getting some odd behavior that I would like to have explained.
Here I am trying to concatenate multiple strings into a variable using =
MyStr = ""
MyStr = "Hello ","Word"
But when I try to run it instead of concatenating I get this error:
Exception has occurred: TypeError
can only concatenate str (not "tuple") to str
After testing with strictly typed types and type identifiers I have come to the conclusion that = treats inputs as a tuple.
Why?
CodePudding user response:
=
doesn't treat input as tuples. The problem is that python treats "Hello", "World"
as a tuple because they are multiple different objects which you are trying to group together. By default, python does this by creating a tuple.
Commas between strings work differently inside print statements, where the two are concatenated automatically by the print function.
So an easy fix should be:
MyStr = ""
MyStr = "Hello " "World"
