Python編程在各行各業(yè)應(yīng)用都十分廣泛,對(duì)于初學(xué)者來說,掌握一些實(shí)用的Python小技巧十分關(guān)鍵,它們可以幫助我們?cè)趯?shí)際的工作中提高效率。接下來筆者列舉一些Python實(shí)用小技巧供各位參考:
names = ['Alice', 'Bob', 'Charlie'] ages = [25, 30, 35] for name, age in zip(names, ages): print(f"{name} is {age} years old")
輸出:
Alice is 25 years old Bob is 30 years old Charlie is 35 years old
fruits = ['apple', 'banana', 'orange'] for index, fruit in enumerate(fruits): print(f"Index {index}: {fruit}")
輸出:
Index 0: apple Index 1: banana Index 2: orange
squares = [x**2 for x in range(1, 6)] print(squares)
輸出:
[1, 4, 9, 16, 25]
fruits = ['apple', 'banana', 'orange'] prices = [0.5, 0.25, 0.75] fruit_prices = {fruit: price for fruit, price in zip(fruits, prices)} print(fruit_prices)
輸出:
{'apple': 0.5, 'banana': 0.25, 'orange': 0.75}
numbers = [1, 2, 3, 2, 1, 4, 5, 4] unique_numbers = set(numbers) print(unique_numbers)
輸出:
{1, 2, 3, 4, 5}
fruits = ['apple', 'banana', 'orange'] if 'apple' in fruits: print("I found an apple!")
輸出:
I found an apple!
numbers = [3, 1, 4, 1, 5, 9, 2, 6, 5] sorted_numbers = sorted(numbers) print(sorted_numbers)
輸出:
[1, 1, 2, 3, 4, 5, 5, 6, 9]
fruits = ['apple', 'banana', 'orange'] fruit_string = ', '.join(fruits) print(fruit_string)
輸出:
apple, banana, orange
希望這些小技巧能對(duì)大家有所幫助!
