Question

我一直在尝试使用python输出csv文件。它没有引号和数字，工作正常。例如：

代码：

for n in G:
    centrality = nx.degree_centrality(G)
    betweeness = nx.betweenness_centrality(G)
    edges = nx.edges(G, n)
    csv_out.writerow([n, str(edges).replace("'",""), round(centrality[n],2), round(betweeness[n],2)])

输出：

24,"[(24, 31), (24, 64)]",0.02,0.04
25,"[(25, 77)]",0.01,0.0
26,"[(26, 49)]",0.01,0.0
27,"[(27, 75), (27, 79)]",0.02,0.02
20,"[(20, 9), (20, 84), (20, 40)]",0.03,0.03
21,"[(21, 77), (21, 64)]",0.02,0.02

我需要能够输入字符串数据。例如：

Automation Specialist I,"[(Automation Specialist I, Data Coordiator)]",0.01,0.0
Community Outreach Specialist,"[(Community Outreach Specialist, Librarian)]",0.01,0.0
Research Assistant III,"[(Research Assistant III, Senior Quality Engineer)]",0.01,0.0
Cost Accountant,"[(Cost Accountant, Structural Engineer)]",0.01,0.0
Data Coordiator,"[(Data Coordiator, Technical Writer), (Data Coordiator, Automation Specialist I)]",0.02,0.01

但是我需要一个引用值才能在前端处理它。像这样：

Automation Specialist I,"[("Automation Specialist I", "Data Coordiator")]",0.01,0.0
Community Outreach Specialist,"[("Community Outreach Specialist", "Librarian")]",0.01,0.0
Research Assistant III,"[("Research Assistant III", "Senior Quality Engineer")]",0.01,0.0
Cost Accountant,"[("Cost Accountant", "Structural Engineer")]",0.01,0.0
Data Coordiator,"[("Data Coordiator", "Technical Writer"), ("Data Coordiator", "Automation Specialist I")]",0.02,0.01

所以我使用下面的代码：

csv_out.writerow([n, str(edges).replace("'",'"'), round(centrality[n],2), round(betweeness[n],2)])

然而，结果如下：

代表数字：

24,"[(""24"", ""31""), (""24"", ""64"")]",0.02,0.04
25,"[(""25"", ""77"")]",0.01,0.0
26,"[(""26"", ""49"")]",0.01,0.0

表示字符串：

Automation Specialist I,"[(""Automation Specialist I"", ""Data Coordiator"")]",0.01,0.0
Community Outreach Specialist,"[(""Community Outreach Specialist"", ""Librarian")]"",0.01,0.0

我还尝试用撇号替换掉引号（列表外），但没有成功。我也尝试使用下面的代码，但它给出了与上面相同的结果。

str(edges).replace("'",'"').replace('""','"')

为了得到我想要的结果，我该怎么做？我计划之后过滤输入的类型，以便仅在字符串时应用该技术。因为如果它是一个数字，理想输出就是第一个例子。当我使用最后一个时，我的前端代码处理文本和数字。但是，当我使用第一个例子时，它不适用于文本，仅适用于数字。

你能帮助我吗？如何将撇号替换为引号？非常感谢你。

Answer 1

尝试用反斜杠转义双引号。例如

str(edges).replace("'","\"")

Answer 2

我最终使用了以下代码：

if(is_number(n) == True):
    edges_w = str(edges).replace("'","")
else:
    edges_w = str(edges).replace("'",'"')

我使用了一个函数来检查它是否是一个数字，然后根据这个函数返回值替换str。我已经考虑过@Stein评论来使用这个解决方案。

如何在Python csv writer中将单引号替换为双引号？
