如何將打印 output 分配給變量

Question

moleculeparse = chemparse.parse_formula(molecule) #Parses the molecular formula to present the atoms and No. of atoms. Molecule here is 'C2H6O2' 
print(moleculeparse) #Print the dictionary

for x,y in moleculeparse.items(): #For every key and value in dictionary
    y = numpy.random.randint(0,y+1) #Randomly generate the value between 0 and y+1
    if y == 0:
        continue
    else:
        y = str(y)
        print(x+y, end = "")

上面的代碼本質上是解析“C2H6O”並將其放入字典中。 然后對於字典中的每個鍵和值，隨機生成值。

運行此代碼時，output 的示例可以是諸如“C1H4”之類的內容，這就是最后一行中的打印語句所做的。 我希望能夠將此 output 分配給一個變量以供以后使用，但我不確定如何執行此操作。 我已經分配了嘗試a = x+y, end = ""但這會導致錯誤。 任何幫助，將不勝感激

Answer 1

這應該是對的

moleculeparse = chemparse.parse_formula(molecule) #Parses the molecular formula to present the atoms and No. of atoms. Molecule here is 'C2H6O2' 
print(moleculeparse) #Print the dictionary

for x,y in moleculeparse.items(): #For every key and value in dictionary
    y = numpy.random.randint(0,y+1) #Randomly generate the value between 0 and y+1
    if y == 0:
        continue
    else:
        y = str(y)
        a = x+y
        print(a, end = "")

Answer 2

最簡單的方法是將每個結果保存在一個列表中，然后將其整理成一個字符串。 您不想“將打印 output 分配給變量”：不需要打印每個結果。

moleculeparse = chemparse.parse_formula(molecule) #Parses the molecular formula to present the atoms and No. of atoms. Molecule here is 'C2H6O2' 
print(moleculeparse) #Print the dictionary

all_results = []

for x, y in moleculeparse.items():  # For every key in dictionary
    y = numpy.random.randint(0,y+1)  # Randomly generate the value between 0 and y+1
    if y == 0:
        continue
    else:
        y = str(y)
        all_results.append(x+y)
in_one_line = "".join(all_results)
print(in_one_line)
