python import問題

先利申: python bb班學員

小弟寫左2個py file + 1個txt file --> temp1.py & temp2.py & config.txt
- config.txt就係define csv file name, report name
- temp1就係根據config.txt入面csv file name去open相關csv file轉做一條n個element既list
如果run temp1.py就會出result_list = [1,...,n]
- temp2.py係用temp1條result_list plot圖:
import temp1
data = temp1.result_list
title_name = temp1.report_name
scat = px.scatter(temp1.result_list, title=title_name)

問題就係config.txt 改左第二個csv file & report name
temp2 run完data同title name冇update到 (即係keep返第一次run既list同report name)
只有熄左pycharm再開/手動run temp1.py先得
想問下可以點解決唔洗run temp1/重開就識update
感激不盡或者話我知用咩Keyword去google

temp1果邊一定要寫做function先得?

利申so

至少叫佢貼埋temp1 出嚟先啦
同埋唔好叫temp1, temp2
改個好啲嘅名

巴打你咁都覆佢真好人

sorry因為temp1只係open csv 同轉做list 我以為冇乜特別同上面位巴打唔同 我temp1唔係function大約係咁:

config_file = r'config.txt'

禁錯
temp1:

config_file = r'config.txt'
c = open(os.getcwd()+'\\' + config_file, "r") 
report_name = get_name('report_name=', ',', 0)
csv_name = get_name('csv file=', settings, ',', 0)
c.close()


.
.
result_list = [1,....,n]

get_name係去拎config.txt入面既str

你貼曬出嚟啦

你明唔明import variable 係做緊咩
如果好似你呢個咁

result_list = [1,....,n] 

咁你咪淨係import咗 [1,....,n]
所以最重要嘅嘢你咁啱就漏咗

如果你右手邊係function
例如
temp1.py

def read_config:
    // read some config
    return csv_file_name
def read_csv:
    // read some data
    return csv_data

csv_file_name = read_csv()

// read_config will be executed
result_list1 = read_csv(csv_file_name)
// read_config will NOT be executed
result_list2 = read_csv()

咁佢都只會為咗計 result_list 而淨係計minimal 有關嘅function
(我唔太肯定import variable behavior，除非import constant 好少咁做)

我覺得係你自己做錯咗咩都唔知
又或者係global local variable 有問題

一般計import functioni 易debug 好多

點樣quote先有syntax highlight
