我有Ubuntu并安装了python3,因为我的脚本是用它编写的.由于我使用MYSQL和MySQLdb,我安装了
apt-get install python-mysqldb
然而,这将MySQLdb安装到Python(在Ubuntu上为2.6)而不是Python3.
对不起,我今天刚开始使用Python ...
我的脚本从文件中读取 MYSQL UPDATE 查询,然后应该使用 autocommit = 0 立即执行它们。但是,如果我删除conn.commit()它,它仍然会一一运行,尽管我没有提交。错误在哪里?
import pymysql
conn = pymysql.connect(host='x', unix_socket='/tmp/mysql.sock',user='x', passwd='x', db='x')
fileHandle = open ( 'mysqlout.txt' )
fileList = fileHandle.readlines()
fileHandle.close()
i = 1
weiter = input("Execute MYSQL file? ")
if (weiter == 'y'):
cur = conn.cursor()
cur.execute('SET autocommit = 0')
conn.commit()
for fileLine in fileList: #-----each line is an UPDATE...query
cur.execute(fileLine)
i = i + 1
print(i," ---",round(i / len(fileList),3))
#conn.commit()
conn.close()

现在我想翻译日费率.我为这个liske getDayRate(日期,货币)写了一个函数.
getDayRate <- function(date, currency) {
currencies[which(as.character(currencies[,c("Date")]) == date),c(currency)]
}
getDayRate("2013-06-20","EUR")

现在我想应用于getDayRate(date,currency)每一行,TRX以便每行使用第一个和第二个元素作为参数,所以我得到了ExchangeRate.
apply(x,1,fun())不起作用,因为它需要一个带数字的矩阵.理论上,我必须将数据帧转换为索引,然后使用apply.
有没有更好的办法?
