R和python中试错运行语句

R中试错运行语句

采用tryCatch({ error = function(e) { } }

for (i in 1:n_subj) { #n_subj Total number of subjects (0D)
  subj <- subjs[i] #subjs List of unique subjects (1D)
  DT_subj <- raw_data[subjID == subj]
  blocks_of_subj <- unique(DT_subj$block_name)
  #subjIndex[i] = subj
  #print(subj)
  
  for (b in 1:b_subjs[i]) { #b_subjs, Number of blocks per each subject 
    curr_block <- blocks_of_subj[b]
    DT_curr_block <- DT_subj[block_name == curr_block]
    #print(curr_block)
    #t <- t_subjs[i, b]
    #blcokIndex[i*b] = curr_block
    
    for (c in 1:feedback_num) { #feedback_num, Number of feedback
      curr_feedback = feedback[c]
      feedback_index = DT_curr_block[feedback_type == curr_feedback, 
                                     which = TRUE]
      nextRESP_index = feedback_index + 1
      
      temp_dishonesty = tryCatch({
        if (tail(nextRESP_index, n = 1) > t_max){ #如果超过t_max界限，去掉最后一个
          nextRESP_index = head(nextRESP_index, -1) 
        }
        temp = DT_curr_block[nextRESP_index, ]
        nrow(temp[whether_dishonesty == 1])/nrow(temp) #计算出不同feedback后下一轮选择欺骗的比例
      },
      error = function(e) {
        #print(paste("subid:  ", subj))
        #print(paste("block:  ", curr_block))
        return(NA)
      })
      subjIndex = c(subjIndex, subj)
      blcokIndex = c(blcokIndex, curr_block)
      feedbackIndex = c(feedbackIndex, curr_feedback)
      dishonesty_ratio = c(dishonesty_ratio, temp_dishonesty)
    }
  }
}

Python中试错运行语句

try:
    import numpy as np # Numeric calculation
    import pandas as pd # General purpose data analysis library
    import squeak # For mouse data
except:
    raise Exception("\
Whoops, you're missing some of the dependencies you need to run this script.\n\
You need to have numpy, pandas, and squeak installed.")
    

Javascript中试错运行语句

JavaScript ( JS ) 是一种具有 函数优先的轻量级，解释型或即时编译型的编程语言。虽然它是作为开发Web 页面的脚本语言而出名的，但是它也被用到了很多 非浏览器环境中，例如 Node.js、 Apache CouchDB 和 Adobe Acrobat。JavaScript 是一种 基于原型编程、多范式的动态脚本语言，并且支持面向对象、命令式和声明式（如函数式编程）风格。了解更多 JavaScript。

**try...catch**语句标记要尝试的语句块，并指定一个出现异常时抛出的响应。

try {
  nonExistentFunction();
} catch (error) {
  console.error(error);
  // expected output: ReferenceError: nonExistentFunction is not defined
  // Note - error messages will vary depending on browser
}
