Basic operators
rounding a // b
a% b modulo
power of a ** ba b
the left and right sides of a == b operator determines whether the same value
a! = b determines whether the value of the left and right sides of unequal operator
a> ba> = ba <ba <= b Comparison operators
Incremental assignment operator
a + = 1 corresponds to a = a +1
a * = 2 corresponds to a = a * 2
...
Chain assignment
x = y =z =1
Cross assignment
a = 1 b =2
a, b = b, a result is a = 2 b = 1
Decompression assignment
l1 = [1, 2, 3, 4, 5]
a, b, c, d, * _ = l1 * _: receiving element may overflow
The result is 1, 2, 3, 4,
