我正在使用 Python 生成用于测试的数据。

我的整个过程几乎可以正常工作，但是，我有这段代码。

def get_lines():

    line1 = "Document Header - Once per document"
    line2 = "\nDocument Information - Once per document"
    line3 = "\nDocument Information 2 - Once per document"
    line4 = "\nUser information 1"
    line5 = "\nUser Information 1"
    line6 = "\nUser Information 1"
    line7 = "\nDocument Footer - Once per document"

    return line1 + line2 + line3 + line4 + line5 + line6 + line7

我想做的是用用户信息 2,3,4 填充第 4,5,6 行，如下所示：

line1 = "Document Header - Once per document"
line2 = "\nDocument Information - Once per document"
line3 = "\nDocument Information 2 - Once per document"   
line4 = "\nUser information 1"
line5 = "\nUser Information 1"
line6 = "\nUser Information 1"  
line4 = "\nUser information 2"
line5 = "\nUser Information 2"
line6 = "\nUser Information 2"
line4 = "\nUser information 3"
line5 = "\nUser Information 3"
line6 = "\nUser Information 3"
line7 = "\nDocument Footer - Once per document"

但是让它随机化，即说我想要 10 个文件，一些将包含一个用户信息，一些 2 一些 3 等等......

我正在努力寻找一种一致的方式来生产我需要的东西。

谢谢你。

你可以喜欢这段代码。

def get_lines():
    line1 = "Document Header - Once per document"
    line2 = "\nDocument Information - Once per document"
    line3 = "\nDocument Information 2 - Once per document"
    line4 = "\nUser information 1"
    line5 = "\nUser Information 1"
    line6 = "\nUser Information 1"
    line7 = "\nDocument Footer - Once per document"

    return setLine(line1, 1) + setLine(line2, 1) + setLine(line3, 1) + setLine(line4, 3)+ setLine(line4, 3, "1", "2")


def setLine(content, iNum = 1, oldStr="", newStr=""):
    strStr = ""
    for ii in range(0, iNum):
    strStr += content.replace(oldStr, newStr)
    return strStr

print(get_lines())

示例代码输出为：

Document Header - Once per document
Document Information - Once per document
Document Information 2 - Once per document
User information 1
User information 1
User information 1
User information 2
User information 2
User information 2

我现在看到您提供了示例数据，但我不确定这是否是您期望从该get_lines方法获得的输出，还是您将要消耗的输入以产生所需的输出get_lines？

只需传递一个带有您要打印的用户标识的变量。您还可以使用random.choice从列表中随机选择一个值或生成并传递一个范围内的随机整数random.randint

def get_lines(userid):

    line1 = "Document Header - Once per document"
    line2 = "\nDocument Information - Once per document"
    line3 = "\nDocument Information 2 - Once per document"
    line4 = "\nUser information {}".format(userid)
    line5 = "\nUser Information {}".format(userid)
    line6 = "\nUser Information {}".format(userid)
    line7 = "\nDocument Footer - Once per document"

    return line1 + line2 + line3 + line4 + line5 + line6 + line7

用户 ID = [1, 2, 3, ,4 ,5, 6, 7, 8, 9]
