Question

我正在使用jupyter笔记本。我想以一般形式打印一个简单的整数矩阵，即我输出如下： a [0] [0] = 1 a [0] [1] = 2 a [1] [0] = 3 a [1] [1] = 4

这是我的计划：

column = int(input("Enter the number of columns: "))
row = int (input("Enter the number of rows: "))
a=[[0 for x in range(column)] for y in range(row)]
for i in range (0, row):
    for j in range (0, column):
        a[i][j]=int(input(" Enter the elements: "))
for i in range (0, row):
    for j in range (0, column):
        print ("a[",i,"][",j,"] =",a[i][j],"\t",),
    print ("\n")

但我得到的输出为：

Enter the number of columns: 2
Enter the number of rows: 2
 Enter the elements: 1
 Enter the elements: 2
 Enter the elements: 3
 Enter the elements: 4
a[ 0 ][ 0 ] = 1     
a[ 0 ][ 1 ] = 2     


a[ 1 ][ 0 ] = 3     
a[ 1 ][ 1 ] = 4

循环中的print（），函数进入一个新行，即使我在它后面加了一个逗号。请帮我获得所需的输出格式。谢谢。

Answer 1

这不会打印新行

print(something,end="")

和你的代码

column = int(input("Enter the number of columns: "))
row = int (input("Enter the number of rows: "))
a=[[0 for x in range(column)] for y in range(row)]
for i in range (0, row):
    for j in range (0, column):
        a[i][j]=int(input(" Enter the elements: "))
for i in range (0, row):
    for j in range (0, column):
        print("a[%d][%d] = %d "%(i,j,a[i][j]),end="")

Answer 2

其他答案都很好，但代码更易读：

some_string = ''
for i in range (0, row):
    for j in range (0, column):
        some_string += "a[{}][{}]= {} ".format(i,j,a[i][j])
print(some_string)

Python中的'print'命令（在同一行中打印）
