Python里导入txt里的数据做计算

so easy import rewith open('lists.txt') as f: s = f.read()alltogether = sum(int(i) for i in re.findall(r'\d+', s))

# 8行结束有一个空白行with open('data.txt') as data: line = 1 sql = 'insert into fz_esx values(%s,%s,%s,%s,%s,%s,%s,%s)' values = [] for d in data: if d != '': values.append('"%s"' % str(d)) if line % 9 == 0: # 执行sql插入代码 #...

filename = r'a.txt'alist = []lines = open(filename,'r').readlines()alist = [line.strip().split(',')[3] for line in lines ]#字段以逗号分隔,这里取得是第4列

data = []for l in open("a.txt"): row = [int(x) for x in l.split()] if len(row) > 0: data.append(row)

with open(txtfilename,'r') as fh: for line in fh.readlines(): print line

import rewith open('num.txt','r') as f : a=f.read()b=re.findall(r'130000000',a)print(len(b))没看懂你要表达啥,不知道这个是不是你想要的。

导入excel(xlsx): # ! /code/pythonwork/python3from openpyxl import load_workbook##读取路径wb = load_workbook(filename=r'C:\Users\Administrator\Desktop\打开excel的位置.xlsx')##读取名字为Sheet1的sheet表ws = wb.get_sheet_by_name...

f = open(sys.path[0]+"\\XXX.txt","r") lines = f.readlines() for line in lines : line=line.strip('\n') data.append(line)

使用open函数打开文件,返回文件句柄 使用文件句柄的read方法读取文件内容 f = open('/path/to/the/file.txt') txt = f.read() txt文件的内容将会读取待txt变量中

python3.x result=[] with open('a.txt','r') as f: for line in f: result.append(list(map(float,line.split(',')))) print(result) python2.7 result=[] with open('a.txt','r') as f: for line in f: result.append(map(float,line.split(',...
