import numpy as np

Nowcoder = np.genfromtxt('Nowcoder.csv',delimiter=',',dtype=str)

# # 方式一
# ls=[]
# for i in range(len(Nowcoder)):
#     msg = Nowcoder[i,0] + Nowcoder[i,1]
#     ls.append(msg)

# result = np.array(ls)
# print(result)

# # 方式二
# result = np.array([Nowcoder[i,0]+Nowcoder[i,1] for i in range(len(Nowcoder))])
# print(result)

# 方式三
Nowcoder_N = Nowcoder.T # 转置操作
result = np.char.add(Nowcoder_N[0],Nowcoder_N[1])
print(result)
