Comparison Operators
- Equality :
== , !=
- Order:
< , > , <= , >=
Assignment Operator
13 == 13
> True
count = 13
print(count)
> 13
Equality Comparisons
- datetimes
- numbers ( float / int )
- dictionaries
- strings
- …
# Comparing dictionaries
d1 = {'high':56.78,'low':33.24,'closing':56.77}
d2 = {'high':56.78,'low':33.24,'closing':56.77}

> True

d2 = {'high':56.78,'low':33.24,'closing':46.01}
print(d1 == d2)
> False
Comparing different types
# Comparing int vs float
print(3 == 3.0)
> True
# comparing int vs string
print(3 == '3')
> False
Not equal operator
print(3 != 4)
> True
print( 3 != 3)
> False
Order operators
- Less than
<
- Less than or equal
<=
- Greater than

>=
print(3 < 4)
> True
print(3 < 3.6)
> True
print('a' < 'b')
> True

Examples
non_cash = 20.33
cash = 19.11
# Assign a value to cash.
cash = 19.11
# Check if cash is equal to non-cash
print(cash == non_cash)
> False
# Assign the value of cash to be equal non-cash
cash = non_cash
# Check if cash is equal to non-cash
print(cash == non_cash)
> True
