یک متغیر میتواند یک نام کوتاه (مانند x و y) یا یک نام توصیفیتر (سن، نام کار، کلحجم) داشته باشد.
نام متغیر فقط میتواند شامل نویسههای عددی و زیرخط باشد (A-z، 0-9 و _ )
متغیرهای درست:
myvar = "John"
my_var = "John"
_my_var = "John"
myVar = "John"
MYVAR = "John"
myvar2 = "John"
متغیرهای نادرست:
2myvar = "John"
my-var = "John"
my var = "John"
نامهای متغیر با بیش از یک کلمه ممکن است به سختی خوانده شوند. چندین تکنیک وجود دارد که میتوانید برای خوانایی بیشتر آنها استفاده کنید:
هر کلمه، به جز کلمه اول، با یک حرف بزرگ شروع میشود:
myVariableName = "John"
هر کلمه با یک حرف بزرگ شروع می شود:
MyVariableName = "John"
هر کلمه با یک کاراکتر زیر خط جدا شده است:
my_variable_name = "John"

اگر مجموعهای از مقادیر در یک لیست، تاپل و غیره دارید، پایتون به شما اجازه میدهد که مقادیر را به متغیرها استخراج کنید. به این کار باز کردن بسته بندی (unpacking) میگویند.
fruits = ["apple", "banana", "cherry"]
x, y, z = fruits
print(x)
print(y)
print(z)
خروجی پایتون
apple
banana
cherry
x = "Python is awesome"
print(x)
خروجی پایتون:
Python is awesome
x = "Python"
y = "is"
z = "awesome"
print(x, y, z)
خروجی پایتون:
Python is awesome
x = "Python "
y = "is "
z = "awesome"
print(x + y + z)
خروجی پایتون:
Python is awesome
x = 5
y = 10
print(x + y)
خروجی پایتون:
15
x = 5
y = "John"
print(x + y)
خروجی پایتون:
TypeError: unsupported operand type(s) for +: 'int' and 'str'
