Python 3.5+ 中的 list() 与可迭代解包

Python 3.5+ 中的 list() 与可迭代解包

python
string = "Hello, World!"
list_string = list(string)
print(list_string)

['H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!']

python
tuple_data = (1, 2, 3, 4, 5)
list_data = list(tuple_data)
print(list_data)

[1, 2, 3, 4, 5]

python
set_data = {1, 2, 3, 4, 5}
list_data = list(set_data)
print(list_data)

[1, 2, 3, 4, 5]

python
data = [1, 2, 3]
a, b, c = data
print(a, b, c)

1 2 3

python
a = 1
b = 2
c = 3
list_data = [a, b, c]
print(list_data)

[1, 2, 3]

python

for word, count in word_count.items():
    print(f"The word '{word}' appears {count} times in the text.")
