每次触发信号时从 QLineEdit 获取不同的输入值
Getting different input values from QLineEdit each time I trigger the signal
我有一段代码(Info_box)
它获取输入值并使用另一段代码 (DataManipulation) 进行一些计算以生成包含所有请求项的数据框。
这是info_box.py:

这是 DataManipulation.py:
import numpy as np
import pandas as pd
a = ''

y = ''
z = ''
j = ''
def DataManipulation(val, val1,val2,val3,val4):
global a, x, y, z, j
try:

except:
print("Invalid Input")
gazoil(a, x, y, z, j)
def gazoil(val, val1, val2, val3, val4):
try:
QU_INITIAL = val
ARR_VENTE = np.array([])
ARR_ACHAT = np.array([])
ARR_ENTREE = np.array([])
ARR_SORTIE = np.array([])

except:
print("Invalid input")
try:
PRIX_VENTE_LT = val1
ARR_VENTE = np.append(ARR_VENTE, PRIX_VENTE_LT)
PRIX_ACHAT_LT = val2
ARR_ACHAT = np.append(ARR_ACHAT, PRIX_ACHAT_LT)
QU_ENTREE = val3
ARR_ENTREE = np.append(ARR_ENTREE, QU_ENTREE)
QU_SORTIE = val4
ARR_SORTIE = np.append(ARR_SORTIE, QU_SORTIE)
QU_STOCK = (val + val3) - (val4)
ARR_STOCK = np.append(ARR_STOCK, QU_STOCK)
MONTANT_VENTE = PRIX_VENTE_LT * QU_SORTIE
ARR_MONTANT_VENTE = np.append(ARR_MONTANT_VENTE, MONTANT_VENTE)

ARR_MONTANT_ACHAT = np.append(ARR_MONTANT_ACHAT, MONTANT_ACHAT)
QU_INITIAL = QU_STOCK
except:
print('merci')
frame = {'Prix de vente': ARR_VENTE, "Prix d'achat": ARR_ACHAT, "Quantité entrée": ARR_ENTREE,
"Quantité sortie": ARR_SORTIE, "Quantité en stock": ARR_STOCK, "Montant Vente": ARR_MONTANT_VENTE,
"Montant achat": ARR_MONTANT_ACHAT}
global result
result = pd.DataFrame(frame)
我想在每次触发信号 (save_btn) 时继续获取一组新的输入，并将前一个数据帧与新数据帧连接起来，以获得一个包含我所有数据的最终漂亮数据帧一直在插入，但似乎没有任何效果。我试图在 gazoil() 中设置一个循环，但是当我第一次点击 save_btn 时，界面会冻结并停止 运行。
为了根据输入进行一些计算，然后每次将它们添加到 DATAFRAME 中，我们可以执行以下操作。
首先我们定义我们将用来存储未来数据帧的数据帧。我们使用 None 来表明数据帧不存在。
self.dataframe = None
然后在单击“保存按钮”按钮后，我们检查输入是否有效。如果不是，我们打印一个错误。否则我们将输入值和当前数据帧传递给函数 data_manipulation.
def save_btn_on_click(self):
try:
input_1 = float(self.line_edit_1.text())
input_2 = float(self.line_edit_2.text())
input_3 = float(self.line_edit_3.text())
except:
print("Invalid input!")
return
self.dataframe = data_manipulation(input_1, input_2, input_3, self.dataframe)
print(f"{self.dataframe}\n")
在data_manipulation中，我们进行基本计算，根据计算创建一个新的数据框，如果存在则将其连接到先前的数据框。
def data_manipulation(input_1, input_2, input_3, previous_dataframes):
print(f"Received inputs: {input_1}, {input_2}, {input_3}\n")
# Some calculation on current inputs
input_1 = input_1 + 2
input_2 = input_2 - 4
input_3 = input_3 * 2
# Creating current dataframe and concatenating to previous dataframes
current_dataframe = pd.DataFrame([{'Calculated input 1': input_1, 'Calculated input 2': input_2, 'Calculated input 3': input_3}])
if previous_dataframes is None:
return current_dataframe
else:
return pd.concat([current_dataframe, previous_dataframes])
