Python–双分裂字符串到矩阵
给定一个字符串,执行双拆分,第一个用于行,第二个用于单个元素,以便给定的字符串可以转换为矩阵。
示例:
输入 : test_str = 'Gfg,bestfor,allgeeks,and,CS ',row _ splt =“”,ele _ splt =“ ”T3】输出 : [['Gfg ',' best'],['for ',' all'],['geeks ',' and ',' CS '] 解释*:字符串按行拆分,元素按各自的 delims 拆分。
输入 : test_str = 'Gfg!最适合!所有极客!还有!' CS ',row_splt = " ",ele_splt = "!" 输出 : [['Gfg ',' best'],['for ',' all'],['geeks ',' and ',' CS']] 解释*:字符串按行拆分,元素按各自的 delims 拆分。
方法#1:使用 split() +循环
在这种情况下,首先使用 split() 构造矩阵的行,然后嵌套 split()以获得单个元素之间的分离。
Python 3
# Python3 code to demonstrate working of
# Double Split String to Matrix
# Using split() + loop
# initializing string
test_str = 'Gfg,best#for,all#geeks,and,CS'
# printing original string
print("The original string is : " + str(test_str))
# initializing row split char
row_splt = "#"
# initializing element split char
ele_splt = ","
# split for rows
temp = test_str.split(row_splt)
res = []
for ele in temp:
# split for elements
res.append(ele.split(ele_splt))
# printing result
print("String after Matrix conversion : " + str(res))
输出:
原字符串为:Gfg,best#for,all#geeks,and,CS 矩阵转换后的字符串:[['Gfg ',' best'],['for ',' all'],['geeks ',' and ',' CS']]
方法 2:使用列表理解+拆分()
这是执行这项任务的另一种方式。在这种情况下,我们使用类似的过程,但单线解决问题。
Python 3
# Python3 code to demonstrate working of
# Double Split String to Matrix
# Using list comprehension + split()
# initializing string
test_str = 'Gfg,best#for,all#geeks,and,CS'
# printing original string
print("The original string is : " + str(test_str))
# initializing row split char
row_splt = "#"
# initializing element split char
ele_splt = ","
# split for rows
temp = test_str.split(row_splt)
# using list comprehension as shorthand
res = [ele.split(ele_splt) for ele in temp]
# printing result
print("String after Matrix conversion : " + str(res))
输出:
原字符串为:Gfg,best#for,all#geeks,and,CS 矩阵转换后的字符串:[['Gfg ',' best'],['for ',' all'],['geeks ',' and ',' CS']]
