我需要將此文件保存在以下相同的文件中,請您對此提供幫助。
10001,Scott,Tiher,100040
10002,Scote,Tijer,100042
10003,Scotr,Tieer,100043
10004,Scotf,Tiler,100044

我嘗試了以下代碼,但無法將b保存到新文件或相同文件中
with open('D:\Programs\python\sql_test.txt','r+') as f:
for line in f:
for word in line.split():
b = str(word[0:5])+ ',' + str(word[5:10]) + ',' + str(word[10:15])+','+ str(word[15:21])
print(b)
您可以with
上下文管理器打開兩個文件:一個用於輸入,另一個用於輸出。
with open("ifilename", 'r') as ifile, open("ofilename", 'w') as ofile:
for line in ifile:
print(','.join([line[0:5], line[5:10], line[10:15], line[15:]]), file=ofile)
這是一種方法
演示:
res = []
with open(filename, "r") as infile:
for i in infile.readlines():
val = i.strip()
res.append([val[:5], val[5:10], val[10:15], val[15:]])
with open(filename, "w") as outfile:
for i in res:
outfile.write(", ".join(i) + "\n")
也許reg
很容易做到這一點:
import re
with open("origin.txt", 'r') as in_fd, open("new.txt", 'w') as out_fd:
for line in in_fd.readlines():
match = re.match(r"([0-9]+)([a-z]+)([0-9]+)", line, re.I)
out_fd.write(','.join(match.groups())+ '\n')
您必須使用f.write(b)
將b
保存到文件中
答案很晚
沒有第二個循環,您的早期解決方案會更好。
如您所知,您不能擁有帶有讀取選項( r
)和寫入( w
)選項的文件。
選項r+
,將轉換后的數據附加到文件末尾。 為了鍛煉,我們將不使用r+
在這里,我們使用f讀取文件,並使用f1寫入結果,最后以\\n
格式化以跳轉行。
In [3]: with open('split.txt','r') as f, open('split2.txt','w') as f1: #one file for read and the other one for saving the result
...: for line in f:
...: output = str(line[0:5])+ ',' + str(line[5:10]) + ',' + str(line[10:15])+','+ str(line[15:21])
...: f1.write("{0}{1}".format(output,"\n")) #outputting with \n to jump to the next line for any new line
