In this section, you’ll learn how to do basic arithmetic, such as addition, subtraction, multiplication, and division, with numbers in Python. Along the way, you’ll learn some conventions for writing mathematical expressions in code.AdditionAddition is performed with the + operator:...
def double(match): return str(int(match.group(0)) * 2) text = "The numbers are 1, 2, 3, and 4" # 使用替换函数参数将所有数字乘以2 new_text = re.sub(r'\d+', double, text) print("替换后的文本:", new_text) # 输出替换后的文本 18. 使用 re.fullmatch() 函数 re.fullmatch(...
读取一般通过read_*函数实现,输出通过to_*函数实现。 3. 选择数据子集 导入数据后,一般要对数据进行清洗,我们会选择部分数据使用,也就是子集。 在pandas中选择数据子集非常简单,通过筛选行和列字段的值实现。 具体实现如下: 4. 数据可视化 不要以为pandas只是个数据处理工具,它还可以帮助你做可视化图表,而且能高度...
