Question

这里的一项产出要求进行多次评价,但得到我想要做的工作(删除除案文外的一切)。

words = IO.read("file.txt").
gsub(/s/, ""). # delete white spaces
gsub(".",""). # delete periods
gsub(",",""). # delete commas
gsub("?","") # delete Q marks
puts words
# output
#      WheninthecourseofhumaneventsitbecomesnecessaryIwanttobelieveyoureallyIdobutwhoamItoblameWhenthefactsarecountedthenumberswillbereportedLotsoflaughsCharlieIthinkIheardthatonetentimesbefore

看看这个员额————我表示,如果不进行多次考试,我将尽力取得相同结果。但我没有获得同样的产出。

words = IO.read("file.txt").
match(/(w*)+/)
puts words
# output - this only gets the first word
# When

这只是第一句:

words = IO.read("file.txt").
match(/(...*)+/)
puts words

# output - this only gets the first sentence
# When in the course of human events it becomes necessary.

任何关于获得相同产出的建议(包括排除白天空间和非口号)与相对比的建议?

Answer 1

你们可以在一项次要行动中做你们想要做的事情:

s =  When in the course of human events it becomes necessary. 
s.gsub /[s.,?]/,   
# => "Wheninthecourseofhumaneventsitbecomesnecessary"

Answer 2

你们不需要对此进行多次评价。

str = "# output - this only gets the first sentence
# When in the course of human events it becomes necessary."
p str.gsub(/W/, "")
#=>"outputthisonlygetsthefirstsentenceWheninthecourseofhumaneventsitbecomesnecessary"
