python怎樣做html的表格

現要實現python制作html格式的表格，利用Python對字符串str.format()格式化操作進行處理，在日常對CVS格式文件處理過程當中，經常會將CVS格式文件進行轉換，在正式場合是程序讀取CVS文件進行轉換並輸出到html格式的文件當中，但現在只是實現壹下轉換的過程，需要輸入以逗號分隔的數據。

在設計程式的時候，需要先定義壹下整個代碼的框架，首先我們要定義壹個主函數main()，雖然Python沒有規定入口函數，壹般在正式的開發中都設計了壹個main()函數作為程序的入口函數，或許這是壹種規範吧。然後我們在定義壹個打印表頭的方法print_head()，並在主函數裏進行調用。再定義壹個打印表尾的方法print_end(),也在主函數中進行調用。定義print_line()為打印表格行，定義extract_field()處理cvs行數據轉換為list集合數據。最後再定義壹個處理特殊符號的方法escape_html()，因為在html代碼中為了避免與它的標簽沖突，特要進行特殊符號的轉換，如&-->&

還有就是對長度過長的數據要進行處理並用...代替

print_end()

#打印表格頭

if line is not None and len(line) > 0:

fields = axtract_fields(line)

for filed in fields:

td = "{0}".format(filed if (len(str(filed)) <= maxWidth) else

(str(filed)[:100] + "..."))

tds += td

tr += "{0}

".format(tds)

print(tr)

#打印表格尾

def print_end():

print("")

#抽取行值

def axtract_fields(line):

line = escape_html(line)

fields = []

field = ""

quote = None

for c in line:

if c in "\"":

if quote is None:

quote = c

elif quote == c:

quote = None

continue

if quote is not None:

field += c

continue

if c in ",":

fields.append(field)

field = ""

else:

field += c

if len(field) > 0:

fields.append(field)

return fields

#處理特殊符號

def escape_html(text):

text = text.replace("&", "&")

text = text.replace(">", ">")

text = text.replace("<", "<")

return text

#程序入口

if __name__ == "__main__":
