datatype-tuple (en)

A tuple is an ordered, immutable collection in Python, usually written with parentheses (), like (1, 2, 3). It’s like a list, but you can’t change it once it’s created.

Create a tuple, then loop over it with for.

tuple1 = (1, 2, 3, 4, 5)
for element in tuple1:
    print(element)

output:

1
2
3
4
5

A tuple can hold mixed types; read elements by index.

# 建立一個 tuple
person = ("Alice", 30, "Engineer")

# 用 index 讀元素
name = person[0]
age = person[1]

print(name)  # Alice
print(age)   # 30

output:

Alice
30

A tuple holds mixed types, and like a list you can read it by index or loop over it.

Unpack a tuple into multiple variables in one go.

person = ("Bob", 25, "Designer")

name, age, job = person   # unpacking
print(name)  # Bob
print(age)   # 25
print(job)   # Designer

output:

Bob
25
Designer
