36. 计算文件中的字符数

with open('file.txt', 'r') as file:
    text = file.read()
    print(len(text))

37. 读取文件中的每一行

with open('file.txt', 'r') as file:
    lines = file.readlines()
    for line in lines:
        print(line.strip())

38. 写入文件

with open('file.txt', 'w') as file:
    file.write("Hello, World!")

39. 计算文件中的单词数

with open('file.txt', 'r') as file:
    text = file.read()
    print(len(text.split()))

40. 生成斐波那契数列

def fibonacci(n):
    fib_series = [0, 1]
    for i in range(2, n):
        fib_series.append(fib_series[-1] + fib_series[-2])
    return fib_series

print(fibonacci(10))
