我想打印的文本文件的選定部分,text.txt
,其中包含:Python的解析選定的區域/文本文件的範圍
tickme 1.1(no.3)
lesson1-bases
lesson2-advancedfurther
para:using the dsp signals are sened via a transmitter to conver to analong signals and gets the output in the form of digital signal
tickme 2.2(no.4)
lesson1-basics2
lesson2-advanced4
para:using the DIGITAL signals are sened via a transmitter to conver to analong signals and gets the output in the form of digital signal
tickme 3.3(no.5)
lesson1-bas
lesson2-adv
para:using the dsp signals are sened via a transmitter to conver to analong signals and gets the output in the form of digital signal
這包括3蜱我,但我想選擇一個特定的tickme 2.2(no.4)在tickme 3.3(no.5)開始之前,我必須解析文本。
因此,如果段落中有「DIGITAL」,則必須打印「lesson1」,因爲它會導致模糊不清,因此我想選擇文本文件的範圍。
輸出:
lesson1-basics2
因爲它有第1課通用於所有蜱我,我需要選擇特定區域tickme2.2之間解析(第4號),以tickme 3.3(第5號)有沒有辦法獲得特定區域的範圍和解析?並且可能會有大量數據在我之間打勾,與示例不同。
問題:它沒有選擇特定的範圍。
searchstring = ""
with open('text.txt','r') as file:
for line in file:
if 'tickme' in line:
searchstring = line
if searchstring != '':
if 'DIGITAL' in line:
print(searchstring)
print(line)
