我对编码和python非常陌生,我认为我正在咬下更多我能咀嚼的东西,但我正在尝试创建一个程序,读取一个包含3列信息的txt文件,然后获取这些列并列出它们。 然后,我想创建一个条件,将第3列的行值与自身上方和下方的行进行比较,如果值的差异大于5,它将复制第1列和第2列中的行,在第3列中找到该值,并将其附加到一个名为spikes的新列表中,我希望可以用它创建一个新的单独的txt文件。 名为“xyz”的txt文件值示例_测试.txt“:”
98015.985 -4922343.462 101.098
98015.985 -4922343.712 101.098
98015.985 -4922343.962 101.093
98015.985 -4922344.212 101.089
98015.985 -4922344.462 108.09
98015.985 -4922344.712 101.095
98015.985 -4922344.962 101.093
98015.985 -4922345.212 101.083
98015.985 -4922345.462 101.081
到目前为止,我能得到并弄清楚的是:
import csv,math listxy = [] listz = [] spikes = [] files =
list(csv.reader(open('xyz_test.txt', 'rb'), delimiter='\t'))
for z in files:
listxy = z[0],z[1]
listz = z[2]
print listz
我得到的结果如下:
101.098
101.098
101.093
101.089
108.09
101.095
101.093
101.083
101.081
现在,我尝试运行一个条件,首先发现列表中的一个数字与其上下数字的差值大于5,但不断出现以下错误:
“并非所有参数都在字符串格式化期间转换”
“无法连接'str'和'int'对象”
有谁能帮我一下吗。你知道吗
Thanks for all the help from everyone, learned allot. i have changed the code to fit what i need , here is what i ended up with. still tweaking , have to create something that sorts the values and loop through several txt files but this is what have so far:
from __future__ import print_function
import pandas as pd
# sets dipslay to larger extent
#pd.set_option('display.height', 10000000)
#pd.set_option('display.max_rows', 5000000)
#pd.set_option('display.max_columns', 50)
#pd.set_option('display.width', 10000)
limit = 3
tries = 0
while True:
print ("----------------------------------------------------")
spikewell = float(raw_input("Please Enter Parameters: "))
tries += 1
if tries == 4:
print ("----------------------------------------------------")
print ("Entered incorrectly to many times.....Exiting")
print ("----------------------------------------------------")
break
else:
if spikewell > 50:
print ("parameters past limit (20)")
print ("----------------------------------------------------")
print (tries)
continue
elif spikewell < 0:
print ("Parameters cant be negative")
print ("----------------------------------------------------")
print (tries)
continue
else:
spikewell
print ("Parameters are set")
print (spikewell)
print ("Searching files")
print ("----------------------------------------------------")
terrain = "1_tile_test.txt"
for df in terrain:
df = pd.read_csv('1_tile_test.txt', sep=r'\s+', names=['____x____ ','____y____ ','____z____'])
# print orginal data frame (for testing)
# get spikes's coordinates
# df['col3'].shift(1) - previous value of the 'col3' column
# df['col3'].shift(-1) - next value of the 'col3' column
spikes = df.loc[(df['____z____'] - df['____z____'].shift(1) > spikewell) & \
(df['____z____'] - df['____z____'].shift(-1) > spikewell)]
wells = df.loc[-((df['____z____'] - df['____z____'].shift(1) > spikewell)) & \
-((df['____z____'] - df['____z____'].shift(-1)) > -spikewell)]
# print and save spikes
# print(spikes[['col1', 'col2','col3']])
# print(spikes2[['col1', 'col2','col3']])
# print(wells[['col1', 'col2','col3']])
# print(wells2[['col1', 'col2','col3']])
spikes[['____x____ ','____y____ ','____z____']].to_csv('spikes.txt', sep='\t', index=False)
#spikes2[['____x____ ','____y____ ','____z____']].to_csv('spikes.txt', sep='\t', index=False)
wells[['____x____ ','____y____ ','____z____']].to_csv('wells.txt', sep='\t', index=False)
#wells2[['____x____ ','____y____ ','____z____']].to_csv('wells.txt', sep='\t', index=False)
print ("----------------------------------------------------")
print ('Search completed')
break
break
你可能想仔细看看pandas
输入数据(出于测试目的,我添加了一行[col3==111.110]):
代码:
输出:
你知道吗尖峰.csv地址:
举个例子:
输出(中间行为“峰值”):
演练:
首先,我们使用csv模块读取整行数据,该模块为我们拆分数据。确保正确设置分隔符。您也可以手动读取它们,但这是更通用的。你知道吗
其次,我们压缩所有
threes
(如三行),并使用is_spike
函数检查它们是否形成一个“尖峰”,这个函数非常简单。你知道吗祝你好运。你知道吗
