Answer: A) 45
The trick: p and q are strings, not numbers!
› p+q = "7"+"2" = "72" (concatenates)
› q+p = "2"+"7" = "27" (concatenates)
› int("72")-int("27") = 72-27 = 45
For beginners: + concatenates strings! If they were numbers, p+q=q+p and result would be 0.

Both p and q are defined as strings.
The plus sign with strings concatenates them. Thus
print(p+q) = 72
print(q+p) = 27
Later these output are type cast to int to perform subtraction which yields 45
English
@Python_Dv Answer:-(A)45
Here p and q are two strings.
Step1:- p+q means concatenate two strings
So, p+q="72" then convert it into integer. So first part become 72(int).
Step2:- q+p="27" again convert it in integer 27.
Step3:- 72-27= 45
So correct answer is 45.
English
@Python_Dv p = "7"
q ="2"
print(int(p+q) - int(q+p)) #(7 + 2) = 72 - (2 + 7) = 27
# 72 - 27 = 45
#A) 45
72 -27
English
@Python_Dv A. 45
1st it will concentrate the string then converted into integer
So 72-27
=45
English
@Python_Dv Answer: A
Concatenate p and q respectively because not are strings then subtract the results which are integers , it gives you 45.
English
@Python_Dv It is a not number,it is a string
P="7"
q="2"
Print(int(p+q)-int(q+p))
P+q=72
q+p=27
72-27=45
Ans:45
English
@Python_Dv String concatenation disguised as arithmetic.
‘72’ − ‘27’ = 45 — the kind of trick that reminds you why context matters in both code and cognition.”
English
@Python_Dv @grok if int is not included what's the answer and give reasons
English
@Python_Dv Your are concatenating the strings, then subtracting after converting the concatenated strings to integers. So your result is 45
English
@Python_Dv Step 1: String concatenation
· p + q = "7" + "2" = "72"
· q + p = "2" + "7" = "27"
Step 2: Convert to integers
· int(p+q) = int("72") = 72
· int(q+p) = int("27") = 27
Step 3: Perform subtraction
· 72 - 27 = 45
Final Answer:
```
45
```
English
@Python_Dv p = "7" and q = "2" are strings. p + q concatenates to "72", and q + p concatenates to "27".
int(p + q) - int(q + p) converts these to integers and subtracts: int("72") - int("27") = 72 - 27 = 45.
