Python for Engineers

Indentation defines blocks. Dynamic typing.

x = 10          # int
name = "BH"     # str
nums = [1,2,3]  # list

Control: if/elif/else, for, while, break/continue

Functions: def, *args, **kwargs, lambda

• list — mutable, ordered
• tuple — immutable
• dict — key→value, O(1) avg
• set — unique, unordered

Comprehensions

[x*x for x in range(10) if x%2==0]

Slicing: a[start:stop:step]

class Student:
    def __init__(self, name):
        self.name = name
