Problem Description
The operators supported by Python mainly include eight operators such as arithmetic, assignment, and comparison. Simple operations can be performed through operators. Operators are not difficult but need to be accurately mastered.
solution
First, you need to master the meaning of various operators, learn the examples in the tutorial, and then practice a few times one by one after you understand, and then compare the examples to find the problems and continue to explore.
1 Arithmetic operators
Master the use of operators such as “+” “-” “*” “/” “%” “**” “//”
username：' or updatexml(1,concat(0x7e,database()),1),1)#
password: just enter
2 Comparison operator
Just like ab, two different variables, to compare these two variables, there are operators such as "==""!="">", if correct, it will return true or 1, and vice versa
a=1
b=2if a==b
print("A equals b")else:print("A is not equal to b")
3 Assignment operator
Use addition and subtraction methods to assign values to variables, with operators such as "=", "+=", and "-="
a=5
b=2
c=0
c=a+b
print("The value of c is:",c)
Conclusion
Before performing operations, familiarize and memorize each operator. Don't make mistakes when entering, master basic operator calculations, and correct them in time based on examples.
