In this example, we open a file namedexample.txtand iterate over each line in the file using a for loop. We use anifstatement to check if the line starts with a ‘#’ character, which is the common way to indicate a comment line in many programming languages. If the line is a comm...

可以使用正则表达式来实现这一目标。例如,在Python中,可以使用以下代码跳过包含特定字符的行: import re pattern = re.compile(r"pattern_to_skip") with open("data.txt", "r") as file: for line in file: if pattern.search(line): continue # 处理不包含特定字符的行 复制代码 总之,在数据清洗过程中,...

We can skip the for loop iteration using continue statement in Python. For loop iterates blocks of code until the condition is False. Sometimes it would
