Task:1
s = "a4k3b2"
1) Write a program to get the output 'abbbbklllbcc'
s = "a4k3b2" output = "" i = 0 while i < len(s): first = s[i] second =s[i + 1] if second.isdigit(): alpha=chr(ord(first)+1) output=output+ first+ (int(second)*alpha) i+=2 print(output)
Output:
abbbbklllbcc
2) Write a program to get the output 'aaaaakkkkbbb'
s = "a4k3b2" output = "" i = 0 while i < len(s): first = s[i] second =s[i + 1] if second.isdigit(): output=output+ first+ (int(second)*first) i+=2 print(output)
Output:
aaaaakkkkbbb
Task:2
matrix = [[10,20,30], [40,50,60], [70,80,90]]
Join the given matrix into single list using comprehensive for and normal for loop.
Method:1(Using normal for loop)
matrix = [[10,20,30], [40,50,60], [70,80,90]] output=[] for i in matrix: for j in i: output.append(j) print(output)
Method:2(Using comprehensive for loop)
matrix = [[10, 20, 30], [40, 50, 60], [70, 80, 90]] output = [j for i in matrix for j in i] print(output)
Output:
[10, 20, 30, 40, 50, 60, 70, 80, 90]
Task:3
l = ['ABC','DEF', 'GHI', 'JKL']
Get OUTPUT: ['ABC', 'def','GHI', 'jkl']
l = ['ABC', 'DEF', 'GHI', 'JKL'] output = [] for i, alpha in enumerate(l): if i % 2 != 0: output.append(alpha.casefold()) else: output.append(alpha) print(output)
Output:
['ABC', 'def', 'GHI', 'jkl']
Transpose Matrix: Transpose of a matrix is obtained by changing rows to columns and columns to rows.
