python operator

 Python provides an if statement with the same semantics as languages like

C++ and Java, although with its own sparse syntax:

if expression1:

suite1

elif expression2:

suite2

else:

suite3

The first thing that stands out to programmers used to C++ or Java is that

there are no parentheses and no braces. The other thing to notice is the

colon: This is part of the syntax and is easy to forget when starting out. Colons

are used with else, elif, and in many other places to indicate that a block of

code (a suite in Python-speak) is to follow. As we would expect, there can be any

number.

Group

Operators

Description

Comparison

<, <=, ==, !=, >=, >

The <> operator is also permitted as a synonym

for != but is deprecated

Identity

is, is not

These are used to determine if two object references refer to the same underlying object

Membership

in, not in These are used on lists, dictionaries, and strings

Logical

not, and,or

Both and and or short-circuit; the bit-wise equivalents are:~ (not), & (and), | (or), and^ (xor)

python basics: effective python ref

pantry = [ ('avocados', 1.25), ('bananas', 2.5), ('cherries', 15), ] for i, (item, count) in enumerate(pantry): print('#%d: %-10s = %.2f' % (i, item, count)) What It Prints (Correctly) #0: avocados = 1.25 #1: bananas = 2.50 #2: cherries = 15.00 #%d → prints the index number (0, 1, 2). %-10s → left-aligns the string (item name) in a field 10 characters wide. Example: "bananas " (adds spaces to align neatly). %.2f → prints the number with 2 decimal places. So the = sign belongs in the format string itself: '%-10s = %.2f' ✅ If you run the exact code above, you will not see separate lines with just the numbers. Instead, you’ll see neatly aligned item + count pairs. 👉 Do you want me to also show you the f-string version (more modern & cleaner than % formatting)? yes Perfect 👍 f-strings make this much cleaner and easier to read. Here’s your same example rewritten with f-strings: pantry = [ ('av...
