holteandtalley软件包需要numpy值,这样做似乎忽略了日期是一回事。考虑日期会怎样?转换为numpy值怎么可能???会成为for循环的for 1/1/2015-> 1/2/2015吗?
<script>
var buyBtn = document.getElementById('payButton');
var responseContainer = document.getElementById('paymentResponse');
// Create a Checkout Session with the selected product
var createCheckoutSession = function (stripe) {
return fetch("stripe_charge.php", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
checkoutSession: 1,
}),
}).then(function (result) {
return result.json();
});
};
// Handle any errors returned from Checkout
var handleResult = function (result) {
if (result.error) {
responseContainer.innerHTML = '<p>'+result.error.message+'</p>';
}
buyBtn.disabled = false;
buyBtn.textContent = 'Buy Now';
};
// Specify Stripe publishable key to initialize Stripe.js
var stripe = Stripe('<?php echo STRIPE_PUBLISHABLE_KEY; ?>');
buyBtn.addEventListener("click", function (evt) {
buyBtn.disabled = true;
buyBtn.textContent = 'Please wait...';
createCheckoutSession().then(function (data) {
if(data.sessionId){
stripe.redirectToCheckout({
sessionId: data.sessionId,
}).then(handleResult);
}else{
handleResult(data);
}
});
});
</script>
e以上表示从csv文件复制的一小部分数据示例。我有3分钟的平均数据,而且很多。
但目标是每天进行h计算,然后将其保存到csv文件中!

如果使用df['data'] = df['data'].strftime('%Y%m%d%H%M').astype(int)
将日期格式更改为整数怎么办?如果您的数据不是pandas datetime格式,那么您还需要第一行代码为:df['data'] = pd.to_datetime(df['data'], dayfirst=True)
df['data'] = pd.to_datetime(df['data'], dayfirst=True)
df['data'] = df['data'].strftime('%Y%m%d%H%M').astype(int)

实际上,您不必将其转换为numpy
,但必须将Pandas Series
转换为list
。 The source code 显示传入的参数由asarray
转换。
