Why we can not subtract strings even if we can add?

Question

Eg: print ('3' +'3') gives 33
print ('3' - '3') gives error

Answer 1

What do you expect from subtracting string? In your case do you expect an empty string? What about "334"-"3", "abc"-"&", "1244"-"4421"?

Well, if there is a rule of subtracting string, it would hardly make sense. To remove a part of the string, you can use slice.

Answer 2

The class string did not implement it.

Answer 3

String subtraction makes no sense, but if you want results like these:
"ABC" - "BC" = "A"
"ABC" - "AB" = "C"

then you can use str.replace method:
"ABC".replace("BC", "") = "A"
"ABC".replace("AB", "") = "B"

str1.replace(str2, str3) gives a copy of string str1, where all occurences of substrings str2 will be replaced with substrings str3.

Answer 4

Because "+" is not only a mathematical operator for summing numbers, but also a concatenation operator that concatenates strings.

Answer 5

LoL!
+ operator on string doesn't add them
It concatenate two strings.

And - sign gives error because programmer of PYTHON didn't add that in syntax

Answer 6

That's not addition, it is concatenation...

Answer 7

Print(name_input())
