2d lists python code example
Example 1: how to input 2-d array in python
matrix = [input().split() for i in range(no_of_rows)]
matrix= [[input() for j in range(no_of_cols)] for i in range(no_of_rows)]
Example 2: how to create 2d list in python
o=[]
for i in range(0,rows):
x=[]
for j in range(0,cols):
x.append(0)
o.append(x)
Example 3: 2d array python
array = [[value] * lenght] * height
//example
array = [[0] * 5] * 10
print(array)
Example 4: create a 2d array in python
def build_matrix(rows, cols):
matrix = []
for r in range(0, rows):
matrix.append([0 for c in range(0, cols)])
return matrix
if __name__ == '__main__':
build_matrix(6, 10)
Example 5: 2d array python3
matrix = [[False for col in range(6)] for row in range(5)]
matrix = [['banana' for col in range(5)] for row in range(6)]
Example 6: We pass in a 2 dimensional list. You should output the 3rd element of the 2nd row.
In a 2 dimensional list, output the 3rd element of the 2nd row.
