在python中，如何在文件的总头中保存一个文件中一定数量的头？

嗨，我有300个标题，但需要在一个文件中保存100-100个标题。你能帮我怎么做吗

例如：

headers = 'chai_patient_id,alcoholstatus_current_drinker,alcoholstatus_non_drinker...................condition_abnormal_results_of_liver_function_studies'

---

我需要在file1.csv中保存1-100个标题，在file2.csv中保存101-200个标题，在file3.csv中保存201-300个标题。您可以尝试以下方法：

import csv
data = "read your data hear"
headers = "your,headers,are,hear,.......,"
headers = headers.split(",")

with open("somefile.csv",'w') as fp:
    some_headers = headers[:100]
    writer = csv.DictWriter(fp,fieldnames=some_headers)
    d = {"header1":"valueone"} # prepare your data
    writer.writeheader()
    writer.writerow(d)
    
repeat above code for multiple files

def chunks(lst, n):
    for i in range(0, len(lst), n):
        yield lst[i:i + n]

for n, headers_chunk in enumerate(chunks(headers.split(','), 100)):
    with open("file{}.csv".format(n), "w") as output_csv:
        for header in headers_chunk:
            f.write(header + ",")
            

---

也许你在找这样的东西：

import csv
data = "read your data hear"
headers = "your,headers,are,hear,.......,"
headers = headers.split(",")

with open("somefile.csv",'w') as fp:
    some_headers = headers[:100]
    writer = csv.DictWriter(fp,fieldnames=some_headers)
    d = {"header1":"valueone"} # prepare your data
    writer.writeheader()
    writer.writerow(d)
    
repeat above code for multiple files

def chunks(lst, n):
    for i in range(0, len(lst), n):
        yield lst[i:i + n]

for n, headers_chunk in enumerate(chunks(headers.split(','), 100)):
    with open("file{}.csv".format(n), "w") as output_csv:
        for header in headers_chunk:
            f.write(header + ",")
            

这将允许您迭代给定大小的块 因此，如果您的标题列表带有

headers.split（'，'）

，您可以这样使用它：

import csv
data = "read your data hear"
headers = "your,headers,are,hear,.......,"
headers = headers.split(",")

with open("somefile.csv",'w') as fp:
    some_headers = headers[:100]
    writer = csv.DictWriter(fp,fieldnames=some_headers)
    d = {"header1":"valueone"} # prepare your data
    writer.writeheader()
    writer.writerow(d)
    
repeat above code for multiple files

def chunks(lst, n):
    for i in range(0, len(lst), n):
        yield lst[i:i + n]

for n, headers_chunk in enumerate(chunks(headers.split(','), 100)):
    with open("file{}.csv".format(n), "w") as output_csv:
        for header in headers_chunk:
            f.write(header + ",")

首先将标题拆分为一个列表，列表之间用逗号分隔。 分离列表文件并将其写入文件列表

   header = header.split(sep=',')
    file1 = header[0:100]
    file2 = header[100:200]
    file3 = header[200:]
    
    with open('file1.txt', 'w') as files:
        files.writelines('%s\n' % head for head in file1)
    
    with open('file2.txt', 'w') as files:
        files.writelines('%s\n' % head for head in file2)
    
    with open('file3.txt', 'w') as files:
        files.writelines('%s\n' % head for head in file3)

这不是一个枯燥的代码，但它确实起到了作用
