下午好
我妻子怀了一个女孩,她的胎龄大约是20周。我一直在尝试创建一个程序,从祖先那里提取我妻子的DNA。com和我一样,做了大量的样本(以防止异常值),然后对我们的女儿(每边50个)进行采样,基本上试图预测我们的基因属于她。
这是我的密码。此时,这些编码都不会返回任何错误:
M = ("England & Northwestern Europe," * 53) + ("Ireland," * 21) + ("Scotland," * 21) + ("Wales," * 5)
M = M.split(',')
M.pop()
len(M)
产量:100
E = ("European Jewish," * 53) + ("Southern Italy," * 31) + ("Levant," * 8) + ("Northern Africa," * 3) + ("Aegean Islands," * 2) + ("Cyprus," * 2) + ("Arabian Peninsula," * 1)
E = E.split(',')
E.pop()
len(E)
产量:100
M_df = pd.DataFrame(M)
E_df = pd.DataFrame(E)
这是我遇到麻烦的手机:
def sample(df1, df2, num): #df1 is for one df, df2 is for the second, and num is for the number of samples.
df1_list = []
df2_list = [] #To keep track of the different columns.
combined_list = []
for x in range(1, num+1):
df1[x] = df1.sample(n=num)
df2[x] = df1.sample(n=num) #To sample a certain amount of times.
df1_list.append(df1[x])
df2_list.append(df2[x]) #Intended to individually number each dataframe as a sample.
combined_list = df1_list + df2_list #Creating a list of all dataframes together.
Baby = pd.concat(combined_list) #An averaged list of all data frames together as a data frame. Essentially the intended output.
sample(E_df, M_df, 50)
